Onchain.DEX.Router.Pool (onchain v0.7.0)

Copy Markdown View Source

A single DEX liquidity pool descriptor consumed by Onchain.DEX.Router.

Two protocols are supported:

  • :uniswap_v2 — constant-product pools. Output is computed analytically in pure Elixir from :reserve0/:reserve1 (no RPC needed for the math). Fetch reserves once via getReserves() and populate the struct.
  • :uniswap_v3 — concentrated-liquidity pools. Output is obtained from the on-chain QuoterV2 contract via eth_call (exact tick-crossing simulation); :reserve0/:reserve1 are ignored.

:fee_bps is the pool fee in true basis points (30 = 0.30%). For v3 it is converted to the uint24 fee tier the quoter expects (fee_bps * 100, so 30 bps → 3000).
