Create Stealth Pool

Build unsigned stealth-pool setup and ER update transactions that map a handle to 1-10 destination owner keys. Requires an Authorization: Bearer <token> header from the /v1/spl/login flow. Once initialized, the handle can be used as the to value of a private /v1/spl/transfer.

POST /v1/spl/stealth-pool

Authorizations

Authorization · string · header · required

Token obtained from the /v1/spl/login flow.

Body

application/json

payer · string · required

Example:

"3rXKwQ1kpjBd5tdcco32qsvqUh1BnZjcYnS5kYrP7AYE"

authority · string · required

Authority allowed to manage the pool.

Example:

"3rXKwQ1kpjBd5tdcco32qsvqUh1BnZjcYnS5kYrP7AYE"

handle · string · required

Human-readable handle, up to 255 UTF-8 bytes. Stored as its exact bytes — NOT trimmed, lowercased, or normalized, so John.Doe@… is a different handle than john.doe@….

Required string length: 1 - 255

Example:

"[e-mail]"

destinations · string[] · required

1-10 destination owner pubkeys (owners, not token accounts).

Required array length: 1 - 10 elements

Example:

[
  "Bt9oNR5cCtnfuMmXgWELd6q5i974PdEMQDUE55nBC57L"
]

splitAcrossKeys · boolean

Optional. When true, split payments may resolve independently across the destination keys.

validator · string

Optional. Validator identity to receive the delegated pool.

Example:

"MAS1Dt9qreoRMQ14YQuhg8UTZMMzDdKhmkZMECCzk57"

cluster · enum<string> string<uri>

Optional. Cluster selector or custom http(s) RPC URL.

Available options: mainnet, devnet, mainnet-private, devnet-private

Example:

"mainnet"

Required range: x >= 0

requiredSigners · string[] · required

stealthPool · string · required

Derived stealth-pool PDA.

setupTransaction · object · required

The base-chain setup transaction. It uses the same transaction response contract as the top-level transaction; sendRpcEndpoint is omitted when sendTo is base.
