Create strategy – Earn API

Updated on
Jul 31, 2026

Overview

Creates a strategy in pending_setup and returns it wrapped in a strategy object (201). Body is a SignedRequest, action strategy.create; the signed payload is the body minus siwe. The recovered wallet owns the strategy; any wallet field in the body is ignored.

Optional idempotencyKey (string, 1-128 chars, else 400) rides inside the signed payload and is scoped per wallet. A repeated key returns the original stored response verbatim, so do not reuse a key across different requests.

Endpoint

POST https://earn-api.quicknode.dev/functions/v1/api/v1/strategies

Authorization

Include the published apikey header and a valid Sign-In with Ethereum (SIWE) proof in the request body. The SIWE message binds the wallet to this action, payload, and request path.

Request body

All fields except siwe are part of the signed payload. Name regex ^[a-zA-Z0-9 _\-.]{1,50}$. chain_ids is an ARRAY of chain ids on input (stored and returned as a CSV string); a missing/invalid chain silently falls back to the first supported chain.

FieldTypeRequiredDescription
siweobjectYesA Sign-In-With-Ethereum proof binding the wallet to (action, payload, issuedAt, expirationTime).
siwe.messagestringYesSIWE message for action `strategy.create`, including the payload hash and `/strategies` path resource.
siwe.signaturestringYesWallet signature over `siwe.message`.
namestringYesStrategy name. Maximum 50 characters; letters, numbers, spaces, underscores, hyphens, and periods are supported.
capital_usdcnumberYesCapital in decimal dollars.
delta_pctnumberNoSame-network APY-gap threshold (percentage points). Optional: when omitted it defaults to the same-network floor. Minimum 3, or 5 when the strategy's networks include Ethereum (chain id 1) — a present value below the floor is rejected with a 400.
cross_chain_delta_pctnumberNoAPY-gap threshold (percentage points) required when the source and destination vaults are on different chains. When omitted, defaults to 0 (inherit delta_pct), so integrations that predate this field keep single-threshold behaviour: one bar gates every move, and later delta_pct updates move both. A split bar is always an explicit opt-in. For a multi-network strategy the EFFECTIVE cross bar (this value when > 0, else the inherited delta_pct) must be >= 5, or >= 7 when the networks include Ethereum — requests below the floor are rejected with a 400.
delta_confirmationsintegerNoNumber of consecutive qualifying APY observations required before rebalancing.
max_positionsintegerYesMaximum number of vault positions. Must be at least 1.
min_tvl_usdnumberNoMinimum vault TVL in decimal US dollars.
min_liquidity_usdnumberNoMinimum vault liquidity in decimal US dollars.
min_liquidity_entry_multipliernumberNoMultiplier on min_liquidity_usd for the non-held entry threshold. Defaults to 2 when omitted.
chain_idintegerNoOptional primary chain id; defaults to the first supported chain.
chain_idsarray<integer>NoChain ids to span. Omit for a single-chain strategy on `chain_id`.
apy_smoothing_minutesintegerNoDefaults to 30 when omitted.
coveredbooleanNoOpt the strategy into OpenCover coverage. Set once at create and immutable thereafter. When true the strategy is forced Base-only (`chain_ids` → "8453") and the wallet MUST be on the covered-access allowlist AND have acknowledged OpenCover's terms, else the create is a 403 (`covered_not_allowed` / `covered_terms_required`). Defaults to false (uncovered).
hidden_vault_keysarray<string>NoVault keys to exclude, formatted as `chainId:0xaddress`.
idempotencyKeystringNoOptional dedupe key (part of the signed payload). A repeat returns the ORIGINAL stored response verbatim, so never reuse a key across logically different requests. Malformed values are 400 `invalid_request`.

HTTP responses

StatusDescription
201The created strategy, wrapped in a `strategy` object.
400Malformed request or SIWE block. `code` is one of: `invalid_request`, `siwe_missing` (no `siwe` block), `siwe_shape` (message/signature not strings), `siwe_parse` (message does not match the documented line format).
401SIWE verification failed. `code` is one of: `siwe_domain` (message domain not allowlisted), `siwe_action` (statement/action mismatch), `siwe_stale` (expired or validity window out of bounds), `siwe_payload` (payload hash or resource mismatch — canonicalization drift, a re-serialized body, or a `- path:` entry that does not match the request path), `siwe_chain` (bad chain id), `siwe_recover` (signature does not match the claimed address), `siwe_replay` (nonce already used — sign a fresh request).
403Covered-access gate (only when the signed payload has `covered: true`). `covered_not_allowed`: the recovered wallet is not on the covered-access allowlist (`approved_wallets`). `covered_terms_required`: the wallet has not acknowledged OpenCover's terms (`POST /v1/wallets/{addr}/opencover-terms`). Both are checked BEFORE any insert; uncovered creates never hit this gate. A failed lookup during the check is a 503 `covered_access_lookup_failed` (fails closed — the boundary never falls through to an insert).
409`hide_floor_violated`: the supplied `hidden_vault_keys` would leave fewer than `max_positions + 1` eligible vaults. Hiding vaults that were never eligible passes. A failed read of the wallet's global hide list is a 503 `hide_lookup_failed`.
429Rate limit exceeded. `Retry-After` (seconds) tells you when to retry. Reads, feedback, and push writes are keyed per IP; create/update/delete are keyed per wallet+IP; deposit/withdraw/claim calldata is keyed per strategy+IP.
500Internal server error.
503Signature verification could not reach the chain to validate a contract (ERC-1271) wallet. Transient — retry. Only occurs for smart-wallet signers.
