Argus and o1

Both pads settle in the same Uniswap v4 singleton on Arc and both publish integration documentation. This page is the integration as built: the contracts read, the record families decoded, and the places where a plausible-looking shortcut returns the wrong number.

Argus

trade + launch

No curve. Whole supply in one Uniswap v4 position, one tax hook per launch.

discovery · argus-portals

Seven Portals. A token always answers from the Portal that created it.
Records are 9, 10 or 11 words; the legacy v3 pair are ten words of different types, so a wrong decode succeeds and returns garbage.

o1

trade + launch

Whole supply into a hooked v4 pool. Multi-chain; Arc quotes in ERC-20 USDC.

discovery · logs

Pays integrators 20 bps of its 100 bps base fee.

Adds liquidity through the PoolManager directly, so no PositionManager NFT exists to enumerate — the Launched event is the only discovery path.
Every token address ends in 01; the creator mines a salt for it.

Argus Portals — every one is indexed

A newer Portal never replaces an older one’s launches: a token keeps answering from the Portal that created it. Records are nine, ten or eleven words, and the two legacy v3 Portals are ten words of entirely different fields — so a wrong decode succeeds and returns plausible garbage. Portal #7 is told from #6 by registry(), because both answer 11 words.

Uniswap on Arc

v4, V3 and V2 are all official Uniswap deployments at chain-specific CREATE2 addresses — not forks. Arc has no canonical WETH: the UnsupportedProtocol stub sits in every WETH slot.

o1 on Arc

Adds liquidity through the PoolManager directly, so no position NFT exists to enumerate — its Launched event is the only discovery path. Every o1 token address ends in 01.
