getStakeMinimumDelegation

getStakeMinimumDelegation returns the smallest amount of SOL that a Solana stake account is allowed to delegate to a validator. The Solana runtime enforces this floor at the protocol level, so a staking flow needs the live value rather than a hardcoded constant. POST a JSON-RPC 2.0 request to https://solana.therpc.io/YOUR_API_KEY and the node returns an RpcResponse whose context carries the slot and whose value is the minimum delegation expressed as a u64 in lamports (1 SOL = 1,000,000,000 lamports).

Use cases

• Validate a user's delegation amount before you build and submit a stake-account creation or delegation transaction, so the network does not reject it for falling below the floor.
• Show the live minimum stake (converted from lamports to SOL) in a staking widget or onboarding flow so users know the smallest amount they can delegate.

Errors & troubleshooting

Common pitfalls

• The returned figure is in lamports, not SOL. Divide by 1,000,000,000 (1e9) before displaying it as a SOL amount, and keep the raw lamports value for any on-chain comparison.
• The number is wrapped in the standard RpcResponse envelope — read result.value, not the top-level result. Treating the whole object as the amount will give you the context block instead of the minimum.
