# Changelog

## 0.55.0

### Added — Arc as a third payment chain

`blockrun_wallet action:"chain" chain:"arc"` pays on Circle's Arc
(eip155:5042) through arc.blockrun.ai, from the same EVM key and address as
Base, funded with USDC on Arc. Arc serves everything Base does. `status`
shows the Base, Solana and Arc balances; the Arc balance is read from the Arc
gateway, or from `ARC_RPC_URL` when set. Setup, the funding QR (EIP-681 on
chain 5042), card top-up guidance and error text name Arc.

Nothing selects Arc automatically: an install that never chose it stays on
the chain it was on.

Requires `@blockrun/llm` 3.25 (Arc's USDC signing domain landed in 3.16).

## 0.54.7

### Fixed — Mistral Large 4 reserves its list price
