The single nominator pool is an alternative type of the TON smart contract designed for validators that have enough self stake to validate by themselves without relying on third-party nominators stakes.

To start using the Staking API and nominate individually with a validator on the TON network:

1. Create a stake transaction.
2. Sign and broadcast it to the network.

Get an authentication token to start using Staking API.

Request examples are provided using cURL.

To create a stake transaction:

1. Send a POST request to /api/v1/ton/{network}/staking/single-nominator/stake.

   Example request (for testnet network):

   cURL

   curl --request POST \
        --url https://api.p2p.org/api/v1/ton/testnet/staking/single-nominator/stake \
        --header 'accept: application/json' \\
    		 --header 'authorization: Bearer <token>' \\
    		 --header 'content-type: application/json' \\
    		 --data '
   {
     "publicKey": "7031f1dcbe0f670daf4094d04ff9a7947bc4ac9174a7d470255d1a664e20b7c6",
     "amount": 1000000000,
     "walletVersion": "V4"
   
   }'
   

   • publicKey — public key of the nominator for the TON network.

   • amount — amount of tokens to stake in nanoTONs (1 TON = 10⁹ nanoTONs). Note that the minimum staking amount is not limited, but there is a maximum cap of 2 000 000 TON for each pool.

   • walletVersion — version of the smart contract used by the wallet in the TON blockchain:

     • V3R1 and V3R2 — wallet V3.
     • V4 — wallet V4; used by default.
     • V5R1 — wallet V5.

   • unsignedTransaction — unsigned transaction in the hexadecimal format. Sign the transaction and submit it to the blockchain to create a staking request.

   • seqno — sequence number of the masterchain block.

   • walletVersion — version of the smart contract used by the wallet in the TON blockchain.

   • stakerAddress — main account address of the bounceable type which keeps tokens.

   • publicKey — public key of the nominator for the TON network.

   • nominatorPoolAddress — Single Nominator Pool address.

   • amount — amount of tokens to stake in TON.

2. Sign and broadcast the unsignedTransaction to the TON network.
