POST/solend/deposit
Cryptographically Attested

Parameters (Kit SDK)

When using @sonabuild/kit, you only provide these parameters. The SDK automatically handles context (wallet, origin) and encryption.

amountnumberrequired

Amount of USDC to deposit (in token units, not lamports)

mintstring

Token mint address (optional, defaults to USDC)

symbolstring

Token symbol (optional, defaults to USDC)

Full Request Schema (Direct API)

If calling the API directly (without Kit), send this complete structure. The Kit SDK constructs this automatically from your params.

encryptedstringrequired

Sealed box encrypted payload

hintobjectrequired

Plaintext hint for hint verification

contextobjectrequired
walletstringrequired

User wallet public key

originstringrequired

Request origin URL

paramsobjectrequired
amountnumberrequired

Amount of USDC to deposit (in token units, not lamports)

mintstring

Token mint address (optional, defaults to USDC)

symbolstring

Token symbol (optional, defaults to USDC)

includeAttestationboolean

Whether to include attestation in response

Cryptographic Attestation

This endpoint generates transactions in a secure enclave. Every transaction includes a cryptographic attestation that can be verified before signing.

Calling directly without the SDK? See our Manual Encryption Guide to learn how to encrypt payloads for attested endpoints.
