Example:

"Bearer 1234567890"

Body

application/json
​
from
string
required

Sender wallet pubkey.

Example:

"3rXKwQ1kpjBd5tdcco32qsvqUh1BnZjcYnS5kYrP7AYE"

​
to
string
required

Recipient wallet pubkey.

Example:

"Bt9oNR5cCtnfuMmXgWELd6q5i974PdEMQDUE55nBC57L"

​
mint
string
required

SPL mint pubkey.

Example:

"EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v"

​
amount
integer
required

Base-unit amount as an integer JSON value with minimum 1.

Required range: x >= 1
Example:

1000000

​
visibility
enum<string>
required

Use public for a transparent SPL transfer or private to route through the Private Ephemeral Rollup.

Available options:
public,
private
​
fromBalance
enum<string>
required

Where the sender's balance is held. Drives which RPC the API uses for blockhash and where the client should submit.

Available options:
base,
ephemeral
​
toBalance
enum<string>
required

Where the recipient should receive the funds.

Available options:
base,
ephemeral
​
cluster

Optional. Use mainnet for BASE_RPC_URL and EPHEMERAL_RPC_URL, devnet for BASE_DEVNET_RPC_URL and EPHEMERAL_DEVNET_RPC_URL, or provide a custom http(s) RPC URL to override the base RPC while keeping the configured ephemeral RPC.

Available options:
mainnet,
devnet
Example:

"mainnet"

​
validator
string

Optional. When this transfer route needs a validator and none is provided, the API resolves it from the selected ephemeral RPC via getIdentity.

Example:

"MAS1Dt9qreoRMQ14YQuhg8UTZMMzDdKhmkZMECCzk57"

​
initIfMissing
boolean

Optional. Initialize the transfer queue if missing.

​
initAtasIfMissing
boolean

Optional. Initialize associated token accounts if missing.

​
initVaultIfMissing
boolean

Optional. Initialize the vault if missing. Defaults to false.

​
memo
string

Optional. Appends a final Memo Program instruction with this UTF-8 message.

Example:

"Order #1042"

​
minDelayMs
string

Optional. Private transfer only. Defaults to 0. Earliest (ms) the queued transfer may settle.

Pattern: ^\d+$
Example:

"0"

​
maxDelayMs
string

Optional. Private transfer only. Defaults to 0 when omitted, or to minDelayMs when only minDelayMs is set. Must be >= minDelayMs.

Pattern: ^\d+$
Example:

"0"

​
clientRefId
string

Optional. Private transfer only. Encrypted client reference ID that can be used to confirm a payment.

Pattern: ^\d+$
Example:

"42"

​
split
integer

Optional. Private transfer only. Defaults to 1. Number of queue entries to split the transfer across. Must be between 1 and 15 and cannot exceed amount.

Required range: x <= 15
Example:

1

​
gasless
boolean

Optional. When true, the API uses the configured sponsor as transaction fee payer and prepends a relay-fee token transfer to the sponsor ATA.

Example:

true

​
legacy
boolean

Optional. Defaults to false. When true, skips lookup-table compilation and returns a legacy transaction. Private base -> base transfers may otherwise return a v0 transaction when a useful lookup table is configured.

Response

Unsigned serialized transaction
