Platform Chain (P-Chain) API

This API allows clients to interact with the P-Chain, which maintains Avalanche’s validator set and handles blockchain creation.

Endpoint

/ext/P

Format

This API uses the json 2.0 RPC format.

Methods

platform.addDelegator

Add a delegator to the Primary Network.

A delegator stakes AVAX and specifies a validator (the delegatee) to validate on their behalf. The delegatee has an increased probability of being sampled by other validators (weight) in proportion to the stake delegated to them.

The delegatee charges a fee to the delegator; the former receives a percentage of the delegator’s validation reward (if any.) A transaction that delegates stake has no fee.

The delegation period must be a subset of the period that the delegatee validates the Primary Network.

Note that once you issue the transaction to add a node as a delegator, there is no way to change the parameters. You can’t remove a stake early or change the stake amount, node ID, or reward address. Please make sure you’re using the correct values. If you’re not sure, check out our Developer FAQ or ask for help on Discord.

platform.addValidator

Add a validator to the Primary Network. You must stake AVAX to do this. If the node is sufficiently correct and responsive while validating, you receive a reward when end of staking period is reached. The validator’s probability of being sampled by other validators during consensus is in proportion to the amount of AVAX staked.

The validator charges a fee to delegators; the former receives a percentage of the delegator’s validation reward (if any.) The minimum delegation fee is 2%. A transaction that adds a validator has no fee.

The validation period must be between 2 weeks and 1 year.

There is a maximum total weight imposed on validators. This means that no validator will ever have more AVAX staked and delegated to it than this value. This value will initially be set to min(5 * amount staked, 3M AVAX). The total value on a validator is 3 million AVAX.

Note that once you issue the transaction to add a node as a validator, there is no way to change the parameters. You can’t remove stake early or change the stake amount, node ID, or reward address. Please make sure you’re using the correct values. If you’re not sure, check out our Developer FAQ or ask for help on Discord.

  • Validating: The blockchain is being validated by this node.
  • Created: The blockchain exists but isn’t being validated by this node.
  • Preferred: The blockchain was proposed to be created and is likely to be created but the transaction isn’t yet accepted.
  • Unknown: The blockchain either wasn’t proposed or the proposal to create it isn’t preferred. The proposal may be resubmitted.

}) -> {status: string}

status is one of:

  • Committed: The transaction is (or will be) accepted by every node
  • Processing: The transaction is being voted on by this node

platform.getUTXOs

Gets the UTXOs that reference a given set of addresses.

Signature

platform.getUTXOs(
    {
        addresses: []string,
        limit: int, //optional
        startIndex: { //optional
            address: string,
            utxo: string

        sourceChain: string, //optional
        encoding: string, //optional
    },
) ->

    numFetched: int,
    utxos: []string,
    endIndex: {
        address: string,
        utxo: string
    },
    encoding: string,
}
  • utxos is a list of UTXOs such that each UTXO references at least one address in addresses.
  • At most limit UTXOs are returned. If limit is omitted or greater than 1024, it is set to 1024.
  • This method supports pagination. endIndex denotes the last UTXO returned. To get the next set of UTXOs, use the value of endIndex as startIndex in the next call.
  • If startIndex is omitted, will fetch all UTXOs up to limit.
  • When using pagination (ie when startIndex is provided), UTXOs are not guaranteed to be unique across multiple calls. That is, a UTXO may appear in the result of the first call, and then again in the second call.
  • When using pagination, consistency is not guaranteed across multiple calls. That is, the UTXO set of the addresses may have changed between calls.
  • encoding specifies the format for the returned UTXOs. Can be either "cb58" or "hex" and defaults to "cb58".

Example

Suppose we want all UTXOs that reference at least one of P-avax1s994jad0rtwvlfpkpyg2yau9nxt60qqfv023qx and P-avax1fquvrjkj7ma5srtayfvx7kncu7um3ym73ztydr.

}' -H 'content-type:application/json;' 127.0.0.1:9650/ext/bc/P

Since numFetched is less than limit, we know that we are done fetching UTXOs and don’t need to call this method again.

Suppose we want to fetch the UTXOs exported from the X Chain to the P Chain in order to build an ImportTx. Then we need to call GetUTXOs with the sourceChain argument in order to retrieve the atomic UTXOs:

curl -X POST --data '{
    "jsonrpc":"2.0",

platform.importAVAX
