Guides

These guides show how to use the Mento SDK v3 for Mento V3: FPMM pools, oracles, route caching, liquidity, and CDP borrowing. The SDK is service-based: after Mento.create(ChainId.CELO) you use mento.tokens, mento.pools, mento.routes, mento.quotes, mento.swap, mento.trading, mento.liquidity, and mento.borrow.
