Staking & DeFi

Carabaas supports native staking operations and DeFi interactions across supported networks. All operations go through the same MPC signing flow and approval pipeline as standard transactions.

Native Staking

Native staking operations are supported on networks with built-in staking mechanisms. These include delegation, undelegation, and reward claiming.

Supported Staking Operations

Operation	Description
Delegate	Stake tokens with a validator
Undelegate	Unstake tokens (subject to unbonding period)
Claim Rewards	Collect accumulated staking rewards
Redelegate	Move stake from one validator to another

Networks with Native Staking

Network	Staking Type	Unbonding Period
Cosmos Hub	Delegation	21 days
Polkadot	Nomination	28 days
Solana	Delegation	~2 days
Cardano	Delegation	2 epochs
Ethereum	Validator	Variable
Celestia	Delegation	21 days
Sui	Delegation	1 epoch

note

Specific staking transaction creation examples and parameters are being finalized. Contact your account manager for current capabilities.

DeFi Operations

The platform supports DeFi interactions through smart contract execution:

• Token swaps — DEX interactions across supported networks
• Liquidity provision — add/remove liquidity to AMM pools
• Yield farming — deposit into yield-generating protocols
• Lending/borrowing — interact with lending protocols

All DeFi operations go through the same approval pipeline — quorum-based approval ensures no unauthorized DeFi interaction can occur.

ERC-20 Allowances

Before interacting with DeFi protocols on EVM chains, you typically need to set token allowances:

Setup Allowance Flow

curl -X POST \
     -H "Authorization: Bearer $TOKEN" \
     -H "Content-Type: application/json" \
     -d '{
       "vaultId": "kR7mNpX2wQvL9sYhBjD4eT",
       "addressId": "gMP71sR5sNUnGdKFTsNzp6",
       "network": "ethereum-mainnet",
       "asset": "USDT",
       "spender": "0xDeFiProtocolAddress...",
       "amount": "1000000"
     }' \
     https://api.carabaas.com/api/v1/transactions/flows/setup-allowance

Check Current Allowance

curl -H "Authorization: Bearer $TOKEN" \
     https://api.carabaas.com/api/v1/addresses/{addressId}/allowance

Transfer From

Execute an ERC-20 transferFrom after allowance is set:

curl -X POST \
     -H "Authorization: Bearer $TOKEN" \
     -H "Content-Type: application/json" \
     -d '{...}' \

Trustlines

For networks like Stellar and Ripple that require trustlines before receiving tokens:

Check Trustlines

curl -H "Authorization: Bearer $TOKEN" \
     https://api.carabaas.com/api/v1/addresses/{addressId}/trustlines

Create Trustline

curl -X POST \
     -H "Authorization: Bearer $TOKEN" \
     -H "Content-Type: application/json" \
     -d '{
       "addressId": "gMP71sR5sNUnGdKFTsNzp6",
       "network": "stellar-mainnet",
       "asset": "USDC"
     }' \
