How this service works

Build unsigned transactions to enter any DeFi yield — native/liquid staking (ETH, SOL, ATOM), stablecoin lending (USDC/USDT on Aave, Morpho), ERC-4626 vaults, and tokenized RWAs across 80+ networks. Does NOT execute: the caller signs and broadcasts each tx, so keys never leave the caller. Find yield IDs via yields_get_all.

Output

Returns one or more unsigned transaction objects that the caller must sign and broadcast — no execution happens on the API side. Each tx contains the calldata, target contract, value, and chain details needed to enter the specified yield position.

Example use cases

Example prompt

“Build me an unsigned transaction to stake 1.5 ETH into yield ID 'eth-lido-staking' from my wallet 0xAbC...123 so I can review and sign it myself.”

Technical details

Endpoint

POSThttps://mcp.yield.xyz/x402/actions_enter?utm_source=zero.xyz

When to prefer

Use this endpoint when you need to programmatically enter a staking, lending, or vault position across 80+ networks while retaining full custody — the API never holds or moves funds itself. Prefer this over execution-based APIs when the signing wallet must remain client-side, or when you need to inspect, simulate, or batch transactions before broadcasting.

Side effects

Invalid yieldId returns 404 or error indicating yield not found
Malformed wallet address causes validation error
Amount below protocol minimum triggers rejection
Unsupported network or yield type returns capability error
Missing required fields (address, amount, yieldId) returns 400 bad request
Yield protocol temporarily paused or deprecated returns error state

Input

Schema · Request body

Field	Type	Description
amount	string	Human-readable token amount to deposit, e.g. "1.5" (never raw wei)
address	string	Wallet address that will own the position and sign the transactions
yieldId	string	Yield ID from yields_get_all, e.g. "ethereum-eth-lido-staking"
inputToken	string	Deposit token address, for yields accepting more than one deposit token. Required when the yield's enter schema lists inputToken as required. Use "0x" for the native token.
validatorAddress	string	Validator to delegate to, for delegation-based staking yields. Get options from yields_get_validators.
inputTokenNetwork	string	Network of the input token, for cross-chain deposits where it is not on the vault's own network.
