feat(web3): add swap/bridge/dapp module; slim wallet to primitives - #3006

Conversation
Split the two concerns the wallet module was carrying. The wallet is now basic — key/account management plus primitive on-chain operations — and a new `web3` module builds the higher-level DeFi surface on top of it. Wallet (slimmed): - Add BNB Chain (BEP20) as EvmNetwork::BscMainnet (chainId 56) + asset catalog. - Remove prepare_swap / prepare_contract_call (and the Swap/ContractCall PreparedKind variants) from the agent + RPC surface. - Add read-only tx inspection: tx_status / tx_receipt / lookup_tx per chain (EVM/BTC/Solana/Tron) as RPC controllers + agent tools. - Add crate-internal sign_and_broadcast_evm / sign_and_broadcast_solana primitives (sign+broadcast an externally-built unsigned transaction; the Solana path re-signs a deBridge VersionedTransaction blob). Not agent/RPC. web3 (new, src/openhuman/web3/): - Three sub-modules over a shared deBridge backend client + quote store: web3_swap (single-chain swaps), web3_bridge (cross-chain DLN bridges), web3_dapp (generic EVM contract calls). Quotes return a quoteId; the matching *_execute confirms and signs via the wallet primitives. - Wired into the controller registry (core/all.rs) and agent toolset (tools/ops.rs); crypto_agent allowlist + loader tests updated. Docs/catalog: rewrite wallet README, add web3 README, update about_app catalog. Tests: per-chain tx-read + Solana re-sign + EVM raw-sign unit tests, web3 ops/ store/types tests, and a json_rpc_e2e round-trip for wallet tx-reads + web3 gates; existing e2e updated for BNB Chain.

📝 WalkthroughWalkthroughThis PR introduces a complete web3 module for DeFi operations (swaps, bridges, generic dapp calls) alongside new transaction inspection APIs for reading on-chain transaction status, receipts, and lookups across BTC, EVM, Solana, and Tron chains. It adds Binance Smart Chain (BSC) network support and refactors wallet execution to expose internal signing primitives that web3 uses. ChangesWeb3 DeFi and Wallet Transaction Inspection

1-4: ⚡ Quick winUpdate module rustdoc to include BSC support.
The module docs still describe EVM coverage as Ethereum + L2s only; this change now includes BSC mainnet and should be documented to keep runtime behavior/docs aligned.
As per coding guidelines: "Ship new/changed behavior with matching rustdoc comments in Rust; update AGENTS.md or architecture docs when rules or user-visible behavior change".

Inline comments:
In `@src/openhuman/wallet/chains/btc.rs`:
- Around line 382-405: The current code sets success: Some(confirmed) causing
unconfirmed mempool BTC transactions to be reported as failed; update the
TxReceiptInfo construction (the block that uses the local variable confirmed) so
success is left unset for unconfirmed txs — i.e., only set success = Some(true)
when confirmed is true and otherwise set success = None — so pending state is
represented via tx_status and not as a failure.
In `@src/openhuman/wallet/chains/evm.rs`:
- Around line 268-282: When eth_getTransactionReceipt returns null in the block
handling receipt in evm.rs, don't immediately set found: false; instead call
eth_getTransactionByHash (same rpc_call_to with "eth_getTransactionByHash") as
the tx_status fallback: if that call returns a non-null value, return a
TxReceiptInfo with chain: WalletChain::Evm, evm_network: Some(network), hash:
hash.to_string(), found: true, success: None, block_number: None, gas_used:
None, fee_raw: None, raw: the tx JSON (or keep serde_json::Value::Null if you
prefer) to represent a pending transaction; only set found: false when both
eth_getTransactionReceipt and eth_getTransactionByHash are null. Ensure this
logic is implemented where receipt is checked and mirrors the existing tx_status
fallback behavior.
In `@src/openhuman/wallet/chains/solana.rs`:
- Around line 172-186: The decode_shortvec function can parse up to 3 bytes into
a u32 then cast to u16, which silently truncates values > u16::MAX and can
corrupt offsets used by sign_and_broadcast_versioned; change decode_shortvec to
validate the accumulated value before casting: whenever you would return
Ok((value as u16, ...)) (inside the byte-with-0x80==0 branch and after the loop
if reachable) first check if value > u16::MAX (0xFFFF) and return Err("shortvec
overflow") (or similar) if so, otherwise safely cast to u16; keep the existing
max-length check (i >= 3) and error messages but ensure the overflow check
prevents truncation used by sign_and_broadcast_versioned.
In `@src/openhuman/wallet/chains/tron.rs`:
- Around line 365-394: The tx_status function currently treats missing
/wallet/gettransactioninfobyid as NotFound; change tx_status to, when
block_number is None, call tron_post("wallet/gettransactionbyid", json!({
"value": hash })) and inspect the returned object: if that call returns a
non-empty object (tx exists but no receipt) return TxStatusInfo with state =
TxState::Pending and block_number = None, otherwise keep TxState::NotFound;
preserve existing logic for receipt/result parsing and ensure errors from
tron_post propagate as before. Use the existing functions/structs (tx_status,
tron_post, TxState, TxStatusInfo) and the endpoint string
"wallet/gettransactionbyid" to locate where to add the fallback check.
In `@src/openhuman/wallet/defaults.rs`:
- Around line 298-302: The match arm for EvmNetwork::PolygonMainnet sets
native_symbol to "ETH" while native_name is "Polygon (MATIC)"; update the match
expression that assigns (native_symbol, native_name) so
EvmNetwork::PolygonMainnet uses ("MATIC", "Polygon (MATIC)") instead of ("ETH",
"Polygon (MATIC)"), leaving the other arms (EvmNetwork::BscMainnet and the
default) unchanged and ensuring the variables native_symbol and native_name
reflect the correct native asset symbol for Polygon.
In `@src/openhuman/web3/client.rs`:
- Around line 50-65: The debug logs in swap_tx and bridge_tx currently print the
entire request body (sensitive wallet addresses); remove or stop emitting the
raw body in tracing::debug and instead log only non-sensitive correlation fields
(e.g., chain ids, token symbols, request IDs) extracted from the body; update
the swap_tx and bridge_tx functions to build a small redacted log payload (or
call the existing redaction helper used in ops.rs) and pass that to
tracing::debug while keeping the actual body passed to self.inner.post
unchanged.
In `@src/openhuman/web3/ops.rs`:
- Around line 200-203: The calldata validation only checks for the "0x" prefix
(variable calldata from params.calldata) and allows "0x" alone, odd-length
strings, or non-hex characters; update the validation in the function containing
calldata to (1) ensure calldata.len() > 2 (not just the prefix), (2) confirm the
hex payload length (calldata.len() - 2) is even, and (3) validate that every
character after "0x" is a valid hex digit, returning a clear Err like "calldata
must be 0x-prefixed even-length hex" when any check fails; reference the
existing calldata variable and the Err return site to replace the simple
starts_with check.
In `@src/openhuman/web3/web3_tests.rs`:
- Around line 28-74: The tests in web3_tests.rs rely on the process-global store
and call reset_store_for_tests(), making stored_quote_count() assertions racy
under parallel cargo test; update the tests that touch the global QUOTE_STORE
(e.g., execute_requires_confirmation, execute_unknown_quote_is_not_found,
store_quote_is_retained_and_counted) to serialize access by using a test-level
mutex or a test serializing crate (e.g., serial_test) or else change assertions
to be isolated (avoid exact global counts) so calls to reset_store_for_tests(),
store::store_quote, and store::stored_quote_count() cannot be interleaved by
other tests.
In `@tests/json_rpc_e2e.rs`:
- Around line 4134-4163: The test is making web3 gate calls without
authenticating, so failures may be auth errors rather than gate-specific
rejections; before calling post_json_rpc for openhuman.web3_bridge_quote and
openhuman.web3_swap_quote, establish an authenticated session (e.g., perform the
test helper login or obtain/set the session cookie/Authorization header used
elsewhere in tests) so the RPC handler proceeds to gate logic, then assert on
gate-specific failure details (inspect the JSON-RPC error object returned by
post_json_rpc and assert error.code or error.message indicates "same-chain" for
openhuman.web3_bridge_quote and an unsignable-chain/wallet-signing error for
openhuman.web3_swap_quote) rather than just error.is_some(); reference
post_json_rpc, rpc_base, openhuman.web3_bridge_quote and
openhuman.web3_swap_quote when making these changes.

Nitpick comments:
In `@src/openhuman/wallet/defaults.rs`:
- Around line 1-4: The module rustdoc incorrectly states EVM covers only
Ethereum mainnet plus L2s; update the top-level comment to mention that EVM
(WalletChain::Evm parameterized by EvmNetwork) also includes BSC mainnet support
so docs match runtime behavior—edit the module docstring near the existing
comment block referencing WalletChain::Evm and EvmNetwork to explicitly list BSC
(Binance Smart Chain) alongside Ethereum and L2s.
- Around line 482-505: Add unit tests that cover BSC: call network_defaults()
and assert there is an entry for WalletChain::Evm with EvmNetwork::BscMainnet
and that its chain_id equals 56, and validate the default's rpc/env/explorer
mappings (RPC URL, env key and explorer URL fields on that default); also add
tests using find_asset_for_network(WalletChain::Evm,
Some(EvmNetwork::BscMainnet), "<symbol>") to assert BEP20 token metadata
(symbol, decimals and the expected contract address/contract field) is returned
for one or more known tokens; reference network_defaults(),
find_asset_for_network(), EvmNetwork::BscMainnet and WalletChain::Evm to locate
where to add these assertions.

- btc/evm tx_receipt: treat pending (unconfirmed / receipt-null but tx-known) as found with success unset, instead of reporting found=false / failed. - tron tx_status: fall back to gettransactionbyid so freshly broadcast txs report Pending instead of NotFound. - solana decode_shortvec: reject values exceeding u16 range instead of silently truncating (could shift signature/message offsets). - solana sign_and_broadcast: fee_raw is None (dynamic fee unknown at broadcast) rather than a misleading "0"; RawBroadcastResult.fee_raw + Web3ExecutionResult .fee_raw are now Option<String>. - defaults: Polygon native asset is POL/Polygon (was ETH symbol vs Polygon name). - web3 client: redact request bodies in debug logs (wallet addresses); log only chain ids. - web3 dapp: validate calldata is even-length hex, not just 0x-prefixed. - tests: serialize web3 store tests against a shared lock; strengthen e2e web3 gate assertions to match gate-specific messages; cover EVM pending receipt.

Not part of the agent/RPC surface.web3module (src/openhuman/web3/): three sub-modules over a shared deBridge backend client + quote store —web3_swap(single-chain swaps),web3_bridge(cross-chain DLN bridges),web3_dapp(generic EVM contract calls). Quote→confirm→execute, signing delegated to the wallet.crypto_agentallowlist updated.Problem
The wallet module was doing two jobs at once: the low-level multi-chain key/sign/broadcast layer and half-built higher-level DeFi affordances (
prepare_swapagainst a caller-supplied router, genericprepare_contract_call). Swaps were quote-only with no real routing or cross-chain capability. Meanwhile the backend shipped a standardized cross-chain swap/bridge surface backed by deBridge DLN (/agent-integrations/crypto/{routes,swap,bridge}, backend PR #852) that returns ready-to-sign unsigned transactions, with nothing consuming it.Solution
to/data/value; Solana hexVersionedTransaction); the web3 layer resolves the caller's wallet address, calls the backend proxy, and stores a TTL'd, chat-thread-owner-bound quote (same security model as the wallet quote store). On execute it hands the unsigned tx to the wallet's crate-internal signer — keys never leave the wallet.web3_swaprejects cross-chain requests (→web3_bridge);web3_bridgerejects same-chain requests; chain ids the wallet can't sign for are rejected at quote time. deBridge responses are passed through asserde_json::Valuefor fields not explicitly consumed, so upstream shape changes don't break deserialization.Submission Checklist
