Uniswap v2/v3/v4 deployment to Robinhood Chain (chain ID 4663).
Arbitrum Orbit chain, parent L1 mainnet, ArbOS 51, ETH gas token.
Pre-existing infrastructure (not deployed by this run):
- Permit2: 0x000000000022D473030F116dDEE9F6B43aC78BA3 (canonical)
- WETH9: 0x0Bd7D308f8E1639FAb988df18A8011f41EAcAD73 (Robinhood-provided)
- CREATE2 deployer: 0x4e59b44847b379578588920cA78FbF26c0B4956C
Newly deployed:
- v2: UniswapV2Factory, UniswapV2Router02
- v3: UniswapV3Factory, UniswapInterfaceMulticall, QuoterV2, TickLens,
NonfungibleTokenPositionDescriptor (proxy + impl + ProxyAdmin),
NonfungiblePositionManager, NFTDescriptor (library)
- swap-router-contracts: SwapRouter02
- v4: PoolManager, PositionDescriptor (proxy + impl + ProxyAdmin),
PositionManager, V4Quoter, StateView
Deploy was split across two passes. The first attempted full deploy
landed v2/v3 factories on chain but halted on a setOwner(self) no-op
where forge reported a failed receipt due to an Arbitrum gas accounting
edge case. The second pass marked the three already-deployed contracts
as deploy:false with their addresses and ran the remaining 14 txs.
All on-chain wiring verified correct end-to-end.
Ownership held by deployer EOA 0x9701fb0aDe1E269c8f64Ec0C7b3cfADB31A13A52.
Transfer to aliased L1 Uniswap Timelock (0x2BAD8182C09F50C8318D769245BEA52C32BE46CD)
planned in a follow-up after a verification window.
Blockscout source-code verification deferred to a follow-up PR.

Calibur (CaliburEntry) deployed via canonical CREATE2 deployer at the shared vanity address 0x000000009b1d0af20d8c6d0a44e162d11f9b8f00 (salt 0x...eca2ad36bee3874a279d0010). Matches the Calibur address on every other chain that has it (Arc, Tempo, etc.). ERC7914Detector deployed via CREATE2 at 0xc470458fc6a7e43471b31e6a2eb2612215a7102e (same as Arc + Tempo, since the detector's initcode binds the Calibur address as a constructor arg and Calibur lives at the same canonical address everywhere). Pre-deploy verification: - Pectra/EIP-7702 active on Robinhood: confirmed via BLS12-381 G1ADD precompile probe (EIP-2537, bundled with EIP-7702 in Pectra). - CREATE2 deployer at canonical 0x4e59...956C: present. - Calibur target address: empty pre-deploy. Deploy details: - Arbitrum Orbit chain, parent L1 mainnet, ArbOS 51. - Deployer: 0x9701fb0aDe1E269c8f64Ec0C7b3cfADB31A13A52 (swap-test EOA). - CaliburEntry tx: 0xfc5d58bca306b47501d741bbbb88d8278f8f19d2bd44051076525b25d4b85a60 (block 19833, 5,624,905 gas). - ERC7914Detector tx: 0xd25a20ee2c22a20620ab0b73846ca31282be387a0ca618f180697f44fe778d0e (block 19834, 252,606 gas). - Total cost: 0.000588 ETH at 0.1 gwei (`--with-gas-price 300000000`, ~3x base fee for headroom). Broadcast routed through the self-hosted Nitro follower node at localhost:8547 (write-forward to sequencer + local reads), the same RPC setup used for the prior Robinhood v2/v3/v4 deploys.

Redeploys UniversalRouter using the regenerated briefcase (stacked on briefcase initcode in that PR was frozen at a submodule pin that predated the v2.1.1 commit upstream. Deployed: - UniversalRouter (v2.1.1): 0x8876789976decbfcbbbe364623c63652db8c0904 Tx: 0x422569c99e80a452d45680fbf16cf04cd4ae79cd2b0d7a6a89cf6603009ed1fa Initcode hash: 0x6dba80c0116a490d48657845492bb38374489ed49c296ac50614265f97221510 Bytecode size: 26,404 bytes (vs 23,587 for v2.1.0) UnsupportedProtocol (0x7332D11BD10d18A04B119Cd4671a96f3148002c4) is unchanged — same source, same initcode hash, still deployed at the same address. Reused as the `acrossSpokePool` placeholder. Old v2.1.0 UR at 0x248a454ac3584c2a48d1fcb28d3910a6b6ea00af is moved to .history in deployments/json/4663.json and labeled as orphaned. The contract still exists onchain but nothing integrates with it. What v2.1.1 brings over v2.1.0: - PAY_PORTION_FULL_PRECISION command (slot 0x07) with 1e18 precision - Per-hop slippage on v2/v3 swaps (minHopPriceX36) - minHopPriceX36 field added to V4 ExactInputSingleParams struct - Expanded command space mask: 0x3f -> 0x7f - v2 fee-on-transfer slippage fix (uses actual balance change) - OZ audit fixes m01, l03, n05, n08 Verification: - Onchain immutables match expected wiring (SPOKE_POOL = UnsupportedProtocol, V3/V4 position managers, PoolManager). - Bytecode dispatcher contains command 0x07 dispatch (4 instances of PUSH1 0x07 in the deployed bytecode). - Deployed bytecode length matches compiled artifact length (49,095 chars; differences are immutable bake-in only). - V4 smoke test simulation passes against the new UR after updating ExactInputSingleParams struct to include minHopPriceX36 (smoke test update will land separately on david-nick/robinhood-smoke-tests). - Blockscout verification passed on first attempt — no submodule alignment dance needed since briefcase now matches the current submodule pin. Cost: 0.000555 ETH (5.55M gas at 0.1 gwei chain base fee).
forge-chronicles' index regen overwrites named chain labels with "Chain N" fallbacks for chains not in its bundled chains.json. Restore "Tempo Mainnet" (4217) and set "Robinhood Mainnet" (4663) explicitly.

Adds the standard SwapProxy entry to each deployments/json/{chainId}.json
`latest` block, matching the existing schema used by other CREATE2 / vanity
contracts (Permit2, CaliburEntry): {address, proxy, deploymentTxn, timestamp,
commitHash}. CREATE2 salt/initcode/build stay in .swapproxy-deploy/create2.json
(the registry never stores those).
Address 0x0000000085E102724e78eCd2F45DC9cA239Affad on all 13 chains. Timestamps
are the real per-chain deploy block times. Supersedes the legacy 0x02e5 entry
tracked in PR #150/#137.

How Has This Been Tested?
End-to-end smoke tests for v2, v3, and v4 (LP + swap where applicable) were written and dry-run successfully against a local Nitro follower node syncing chain 4663. Scripts live in
script/smoke/(not committed in this PR — they're local validation tools).On-chain sanity check covered:

After deployment
Considerations
Additional context
Robinhood Chain uses an Arbitrum Orbit setup with a sequencer-only write endpoint and a Blockscout read endpoint. The deploy was executed against a self-hosted Nitro v3.10.0 follower node (not committed to repo) that aggregates reads from the L1 batches via Quicknode + a public beacon RPC, and forwards writes to the sequencer.
