What “Exchange Contracts” means on Arc
The AMM side of the chain: factories, and the pools they create. Every name here rests on published evidence — a revert string in the contract's own deployed bytecode, or a factory() call that resolves to a factory whose pools it trades. Where the evidence supports only a shape, the name says the shape: a row reading “V3-compatible Factory” is one Arcscan could not tie to a brand, and calling it Uniswap would be a guess. Only addresses this chain's own index has seen are listed.
| Address | Label | Token | Detail | First Block | Last Block |
|---|---|---|---|---|---|
| AMM Factory (0x284c5afc router) | — | The router 0x284c5afc...66b1, sender of 4,625 Swap events in blocks > 54,100,000, answers factory() with this address. Its own bytecode carries only generic reverts (`Pool exists`, `Identical tokens`, `Insufficient liquidity minted`), so no brand can be asserted. |
An address is a 20-byte identifier that can hold a balance and, when it carries code, execute it. Gas on Arc is paid in USDC, so the balance shown for an address is denominated in dollars rather than in a volatile asset.

| 0xd67F63A4...c8B5743a5 | ArcFlow V25: Factory | — | Deployed bytecode contains `ArcFlowV25: PAIR_EXISTS`, `ArcFlowV25: IDENTICAL_ADDRESSES`, `ArcFlow V25`. Emitted 560 PairCreated events in 54,051,461-54,220,147, and 380 of the 460 addresses that emitted a Uniswap-V2-shaped Swap answer factory() with it — the largest V2 family on the chain by pair count.Bytecode string · measured at block 54,281,486 | 54,281,486 | — |
| 0xa16aF7FC...23b23e3a8 | Arcin V2: Factory | — | Deployed bytecode contains the literal `Arcin V2`. The router 0xa01a6f36...eab9, sender of 598 Swap events in blocks > 54,100,000, answers factory() with this address.Bytecode string · measured at block 54,281,486 | 54,281,486 | — |
| 0x724B24E0...b8f68A8D4 | OnmiFun: Factory | — | Deployed bytecode contains `OnmiFunFactory: FORBIDDEN`, `OnmiFun: PAIR_EXISTS` and the LP token name `Onmifun LPs`. Its pairs carry the LP symbol Onmi-LP — for example 0x95b0d01ebf734178e27ea8c44d654792e1ce9e29.Bytecode string · measured at block 54,281,486 | 54,281,486 | — |
| 0x9DE50a65...9c121821D | Tower: Factory | — | Deployed bytecode contains the revert prefixes `Tower: PAIR_EXISTS`, `Tower: IDENTICAL_ADDRESSES`, `Tower: K`. Pairs that answer factory() with this address carry the LP symbol TOWER-LP — for example 0xfa4cc09c073742b7ea534e0b55b8d2bb3089668c (USDC/EURC), the busiest V2-shaped pair on the chain.Bytecode string · measured at block 54,281,486 | 54,281,486 | — |
| 0x205879F4...31756a210 | V2-compatible Factory (uint256 reserves) | — | Emitted 1,146 PairCreated events in 53,959,833-54,256,240, the most of any V2-shaped factory. 518 of the 541 addresses that emit Sync(uint256,uint256) — the wide-reserve variant, topic0 0xcf2aa508... — answer factory() with it, and those same pairs emit the standard Uniswap-V2 Swap. No brand string in its bytecode; no router of its own was identified.Factory relationship · measured at block 54,281,486 | 54,281,486 | — |
| 0x065b21b2...E7D11a010 | V3-compatible Factory | — | Emitted 46 PoolCreated events in 53,974,730-54,210,026. The router 0xb5d2f3aa...1c7f, sender of 334 Swap events in blocks > 54,100,000, answers factory() with it.Factory relationship · measured at block 54,281,486 | 54,281,486 | — |
| 0x0fB6EEDA...52a27f59c | V3-compatible Factory | — | 58 of the 139 addresses that emitted a Uniswap-V3-shaped Swap answer factory() with this address, including the three busiest pools on the chain (0x1c02648c..., 0x715f78de..., 0x66a038f2...). Two routers name it: 0xa545bcb1...c31b and 0xbf4479c0...275f. Its bytecode carries no brand string, so this is deliberately not given a protocol name.Factory relationship · measured at block 54,281,486 | 54,281,486 | — |
| 0x7E875574...68914c01A | V3-compatible Factory | — | Five of the addresses that emitted a V3-shaped Swap answer factory() with it. The router 0xc2d2829c...de68, sender of 722 Swap events in blocks > 54,100,000, names it.Factory relationship · measured at block 54,281,486 | 54,281,486 | — |
| 0xAb6A8AAb...9688a1971 | V3-compatible Factory | — | Emitted 15 PoolCreated events in 53,976,111-54,220,224; 20 of the 139 addresses that emitted a V3-shaped Swap answer factory() with it. Two routers name it: 0x996ebb17...69a5 and 0x509cf58c...3d01. No brand string in its bytecode. It answers owner() with 0x3682652c...55b8, the same EOA that owns the ArcFlow NFT, which suggests this is ArcFlow's V3 deployment — but a shared owner EOA is a statement about who holds a key, not about what the code is, and the ArcFlow V2 factory exposes no owner() to corroborate it. Recorded as a lead; `protocol` stays null until something stronger than a shared key supports the brand.Factory relationship · measured at block 54,281,486 | 54,281,486 | — |
| 0xBa27C71b...91Fd53A93 | V3-compatible Factory (most pools) | — | Emitted 6,467 PoolCreated(address,address,uint24,int24,address) events in 53,959,754-54,280,912 — more than every other factory on the chain combined. owner() returns 0xd8c7430b...5103. Its pools carry almost no swap volume, and its bytecode has no brand string, so it is named by shape and rank only.Event signature · measured at block 54,281,486 | 54,281,486 | — |
| 0x60EDeFB0...3Ba1979e2 | XyloNet: Factory | — | Deployed bytecode contains `XyloFactory: INVALID_A` alongside the embedded pool creation code (`XyloPool: INVALID_A`, `XyloPool: TOO_EARLY`, `XyloPool: ZERO_ADDRESS`) and the LP-token prefix family `XyloERC20: INVALID_SIGNATURE`. Both labelled XyloNet contracts point at it: the pool 0x3df3966f...3bb1 and the router 0x73742278...1023 each answer factory() with this address. It emits no logs of its own over the indexed range, so it is identified by its bytecode and by the two contracts that name it rather than by a creation event.Bytecode string · measured at block 54,285,491 | 54,285,491 | — |
| 0x3DF3966F...0ce083BB1 | XyloNet: USDC-EURC Pool | — | name() returns `XyloNet USDC-EURC LP`, symbol() `XYLO-USDC-EURC`. Bytecode carries `XyloPool: A_CHANGE_TOO_LARGE` and `XyloPool: INVALID_A` — a stableswap amplification parameter, not a constant-product pair. Emitted 24,340 logs on one Xylo-specific topic in blocks > 54,080,000.Bytecode string · measured at block 54,281,486 | 54,281,486 | — |
