getStakeMinimumDelegation

getStakeMinimumDelegation returns the smallest amount of stake, in lamports, that a stake account is allowed to delegate to a validator. Delegating less than this threshold is rejected by the runtime, so you should query it before building a StakeProgram.delegate instruction and size the delegation at or above the returned value.

The minimum is a cluster-wide parameter that changes only with a feature activation, so the result is effectively constant on a given cluster and is safe to cache. Use it together with the rent-exempt reserve when deciding how much to fund a new stake account: a stake account must hold at least the rent-exempt minimum plus the delegation minimum to be both rent-exempt and delegatable.

Unlike getMinimumBalanceForRentExemption, this method returns an RpcResponseU64 object — the lamports value lives under value, wrapped in the standard context envelope that reports the slot the result was evaluated at.

JSON-RPC params is a positional array with a single optional element: [config?].

Response fields

Errors use the standard JSON-RPC envelope. See errors.md for the full envelope and the complete code table.

const client = new TriportClient({ apiKey: process.env.TRIPORT_API_KEY! });


const { context, value } = await client.solana.getStakeMinimumDelegation({
  commitment: "finalized",

Python (triport-sdk)

import os

resp = client.solana.get_stake_minimum_delegation(commitment="finalized")

print(resp.context.slot)   # 348392041

• The lamports value is under result.value, not the top-level result — this differs from getMinimumBalanceForRentExemption, which returns a bare integer.
• The minimum delegation is a cluster-wide constant that changes only on a feature activation, so it is safe to cache rather than calling on every delegation build.
• A stake account must be funded with the rent-exempt reserve in addition to the delegation minimum. Pair this with getMinimumBalanceForRentExemption to compute total funding, and with getBalance to check an existing stake account's lamports.
