feat(chains): add Arbitrum One (42161) with Aave V3 + Uniswap V3#34
Merged
Conversation
Promotes Arbitrum from a bridge-only destination to a full source chain. The token table (tokens/arbitrum.toml) already existed; this wires up routing + two staple protocols so swap/lending/lp commands work on Arbitrum. chains.toml [chain.arbitrum]: - chain_id 42161, rpc https://arbitrum.drpc.org (matches base's drpc), explorer arbiscan.io, native ETH, wrapped WETH (0x82aF…Bab1), multicall3 canonical - aggregators: kyber + openocean = "arbitrum", lifi/relay = "auto" (LiquidSwap omitted — HyperEVM-only) Protocol configs (addresses verified against official sources): - aave-v3-arbitrum (bgd-labs/aave-address-book AaveV3Arbitrum): pool 0x794a…14aD, addresses-provider 0xa976…3CDb, oracle 0xb56c…C7C7, data-provider 0x243A…c43b - uniswap-v3-arbitrum (developers.uniswap.org v3 deployments): factory 0x1F98…F984, router(SwapRouter02) 0x68b3…5Fc45, quoter(QuoterV2) 0x61fF…0B21e, position-manager 0xC364…1FE88 Live read-only check: `lending rates --protocol aave-v3-arbitrum --asset USDC` returns real market data (supply 2.97% / borrow 3.87% / util 85.53%), confirming the adapter + multicall path resolve against mainnet. (arbitrum.drpc.org showed intermittent "Temporary internal error" — transient RPC flakiness, ~1/3 calls; retryable.) chain-id.test.ts: drop arbitrum from KNOWN_ORPHAN_TOKEN_TABLES (it's now registered) + add arbitrum:42161 to the canonical chain_id map.

Banner count is computed dynamically from the registry, but the README / SKILL.md / protocols.md prose hardcodes the totals. Update all mirrors to 6 chains · 41 protocols (+arbitrum, +2 protocols): - README.md (root + ts/packages): banner line - SKILL.md (both mirrors): header count, --chain flag list, Chains table (+arbitrum 🟡 staged), references count - protocols.md (both mirrors): new Arbitrum section (aave-v3-arbitrum, uniswap-v3-arbitrum) + aggregator support table (kyber/openocean now list arbitrum) Arbitrum is marked 🟡 staged: addresses verified + read path live-confirmed, but no funded broadcast yet (matches monad). The slug-parity test enforces byte-identical ts/root mirrors, so both copies are updated together. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

Summary
Promotes Arbitrum One (chain_id 42161) from a bridge-only destination to a full source chain. The token table already existed (
tokens/arbitrum.toml); this wires up routing + two staple protocols soswap/lending/lpwork on Arbitrum.Banner: 5 chains · 39 protocols → 6 chains · 41 protocols.
