Solana

Solana uses an account-based model with unique requirements for token handling — each token requires an Associated Token Account (ATA) to be created before receiving.

SPL Token Transfers​

Transfer SPL tokens using the standard transaction endpoint:

curl -X POST \
     -H "Authorization: Bearer $TOKEN" \
     -H "Content-Type: application/json" \
     -d '{
       "orderId": "a9b0c1d2-e3f4-4a5b-6c7d-8e9f0a1b2c3d",
       "vaultId": "kR7mNpX2wQvL9sYhBjD4eT",
       "destination": "SolRecipient...",
       "network": "solana-mainnet",
       "asset": "c501_tEPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v",
       "amount": "1000.00",
       "feePriority": "medium"
     }' \

The platform handles ATA creation automatically when sending to an address that doesn't have a token account yet.

Fee Payer​

On Solana, transaction fees are paid in SOL by the transaction signer. Use the feePayer option to specify a different address to cover the fee — useful when the source address only holds SPL tokens and no SOL:

curl -X POST \
     -H "Authorization: Bearer $TOKEN" \
     -H "Content-Type: application/json" \
     -d '{
       "orderId": "b0c1d2e3-f4a5-4b6c-7d8e-9f0a1b2c3d4e",
       "vaultId": "kR7mNpX2wQvL9sYhBjD4eT",
       "addressId": "mK4nP6qR8sT0uV2wXyZaBc",
       "destination": "SolRecipient...",
       "network": "solana-mainnet",
       "asset": "c501_tEPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v",
       "amount": "500.00",
       "options": {
         "feePayer": "jL5mN7pQ9rS1tU3vWxYzAb"
       }
     }' \
     https://api.carabaas.com/api/v1/transactions

The feePayer must be an address in the same vault that holds sufficient SOL to cover the transaction fee. This is especially useful for:

  • SPL-only addresses that receive token deposits but don't hold SOL
  • Centralized fee management where one address covers fees for many token transfers
  • Customer deposit sweeping where deposit addresses hold only tokens

Staking (Delegation)​

Solana supports native staking through delegation to validators:

curl -X POST \
     -H "Authorization: Bearer $TOKEN" \
     -H "Content-Type: application/json" \
     -d '{
       "orderId": "c1d2e3f4-a5b6-4c7d-8e9f-0a1b2c3d4e5f",
       "vaultId": "kR7mNpX2wQvL9sYhBjD4eT",
       "addressId": "gMP71sR5sNUnGdKFTsNzp6",
       "destination": "ValidatorVoteAccount...",
       "network": "solana-mainnet",
       "asset": "c501",
       "amount": "100.0",
       "options": {
         "type": "delegate"
       }
     }' \
