Generate deposit calldata – Earn API

Aktualisiert am
Jul 31, 2026

Übersicht

Returns one ready-to-sign selfBatchDeposit transaction on the strategy's chain, covering local vault deposits plus per-remote-chain CCTP burns. The matching intent (kind deposit) is written server-side; do not post an intent separately. No auth; no request body (the id is in the path).

Strategy must be pending_setup (top-ups are not supported).

Timing: expiresAt is an advisory ~1h plan-freshness bound. The intent itself has a 30-day TTL; regenerating an unchanged plan within it returns the same intentId, and regenerating after expiry or fulfillment mints a new one. A strategy that has never received a deposit is purged about one hour after it was last touched, taking its intent with it; calling this endpoint refreshes that hour. If signing takes longer than an hour (e.g. a multisig), regenerate at least hourly until the transaction is broadcast.

Approve vault share tokens and USDC before calling: live allowances affect vault selection, and approvalsNeeded reflects what is still missing.

Submit the returned Daten verbatim (re-encoding breaks intent attribution) and use gasHint as the gas limit (wallet re-estimates can run out of gas).

Endpoint

POST https://earn-api.quicknode.dev/functions/v1/api/v1/strategies/{id}/calldata/deposit

Authorization

Include the published apikey header. This endpoint is public and does not require a SIWE signature.

Rate limits

This operation belongs to the calldata rate-limit bucket. It allows 10 requests per 60 seconds, keyed by strategy+ip. A coarser limit of approximately 30 requests per 60 seconds also applies per IP across deposit, withdrawal, and claim calldata requests.

Parameter

ParameterLocationTypErforderlichBeschreibung
idpathZeichenketteJaStrategy UUID.

Request body

Deposit calldata request body. Public (no SIWE). The deposit endpoint takes no parameters, so send no body or an empty JSON object ({}).

Example request

curl --request POST \
--url 'https://earn-api.quicknode.dev/functions/v1/api/v1/strategies/<PENDING_STRATEGY_ID>/calldata/deposit' \
--header 'Accept: application/json' \
--header 'apikey: <EARN_PUBLIC_API_KEY>' \
--header 'Content-Type: application/json' \
--data '{}'

Antwort

FeldTypErforderlichBeschreibung
kindstring (deposit)JaIdentifies the response as a deposit calldata plan.
Transaktionenarray<object>JaExactly one transaction, on the strategy's chain.

transactions[].intentIdZeichenketteJaIntent UUID used to track the transaction.
transactions[].kindstring (deposit)JaTransaction intent kind.
transactions[].descriptionZeichenketteJaHuman-readable transaction summary.
transactions[].gasHintstring | nullJaRecommended gas limit, or `null` when it cannot be estimated.
transactions[].gasHintReasonZeichenketteNein`approvals_required` or `estimation_failed` when `gasHint` is `null`.
approvalsNeeded[].chainIdGanzzahlJaChain where approval is required.
approvalsNeeded[].tokenZeichenketteJaToken contract requiring an allowance.
approvalsNeeded[].spenderZeichenketteJaQuicknode Earn proxy address.
approvalsNeeded[].currentAllowanceZeichenketteJaCurrent allowance in token base units.
approvalsNeeded[].requiredAllowanceZeichenketteJaRequired allowance in token base units.
approvalsNeeded[].txObjektJaReady-to-sign token approval transaction.
approvalsNeeded[].tx.toZeichenketteJaToken contract receiving the approval call.
approvalsNeeded[].tx.dataZeichenketteJaABI-encoded approval calldata.
approvalsNeeded[].tx.valueZeichenketteJaNative-token value, normally `"0"`.
plan.totalUsdcZeichenketteJaTotal allocated USDC as a six-decimal base-unit string.
plan.vaultsarray<string>JaLocal-chain vault addresses.
plan.amountsarray<string>JaBase-unit amounts aligned with `plan.vaults`.
plan.burnsarray<object>JaCombined CCTP burns for remote chains.
plan.burns[].destDomainGanzzahlJaCCTP destination domain.
plan.burns[].mintRecipientZeichenketteJaBytes32-padded mint recipient.
plan.burns[].destinationCallerZeichenketteJaBytes32-padded destination caller.
plan.burns[].amountZeichenketteJaBurn amount in USDC base units.
plan.burns[].maxFeeZeichenketteJaMaximum CCTP fee in base units.
plan.burns[].minFinalityThresholdGanzzahlJaMinimum CCTP finality threshold.
plan.burnVaultBreakdownarray<array<object>>JaDestination vault allocations aligned with `plan.burns`.

HTTP responses

StatusBeschreibung
200One deposit transaction, approvals needed, plan transparency, and an advisory expiry.
400One of: the strategy is not `pending_setup` (`invalid_state`); no eligible vaults (`no_eligible_vaults`); gas estimation failed (`gas_estimation_failed`, the tx would revert, usually unfunded or unapproved); or a malformed JSON body (`invalid_request`).
404Resource not found.
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 error, or `burn_route_unavailable` when a required remote chain has no CCTP burn route configured.
503The hide list could not be loaded (`hide_lookup_failed`, fails closed).
