Deposit with the [manage endpoint](https://docs.compasslabs.ai/v2/api-reference/earn/manage-earn-position) using `{"type": "MAPLE", "pool_address": ...}`: shares are minted directly from Maple at the pool exchange rate, and the Earn Account is authorized with Maple automatically on its first deposit. Withdrawals are asynchronous (Maple's withdrawal queue, typically minutes, at most 30 days); to exit immediately at market price, use the [swap endpoint](https://docs.compasslabs.ai/v2/api-reference/earn/swap-tokens). Maple pools are on Ethereum; other chains return an empty list. ## OpenAPI ````yaml /v2/combined_spec.json get /v2/earn/maple_pools openapi: 3.1.0 info: title: Compass API description: Compass Labs DeFi API version: 0.0.1 servers: - url: https://api.compasslabs.ai description: Production server security: - ApiKeyAuth: [] paths: /v2/earn/maple_pools: get: tags: - Earn summary: List maple pools description: >- List the Maple syrup pools (syrupUSDC, syrupUSDT) available through the `MAPLE` venue, with exchange rate, TVL, 7-day APY and withdrawal-queue state.
