Node-operator SDK for the Solinkify DePIN relay network on Solana: staking tiers, PDA helpers, weighted-score and epoch-reward math, and thin instruction wrappers for register_node / add_stake / unstake / claim_reward — everything mirrors the on-chain program, so what you compute locally is what the contract enforces.

Run a node, relay Solinkify traffic (Jalur B), earn a share of protocol fees: 0.375% of every relayed payment goes to the relaying node directly plus 0.375% into the epoch reward pool, split by weighted score.

Install

npm install @solinkify/depin @coral-xyz/anchor @solana/web3.js @solana/spl-token

Staking tiers (tokenomics v2, enforced on-chain)

Tier	Min stake	Multiplier
Lite	25 $SINKY	1.0×
Bronze	100 $SINKY	1.0×
Silver	500 $SINKY	1.5×
Gold	2,000 $SINKY	2.5×

import { getTierFromStake, TIER_THRESHOLDS, MIN_STAKE, formatSinky } from '@solinkify/depin';

getTierFromStake(2_000n * 1_000_000_000n); // 'Gold'  (raw units, 9 decimals)

Reward weight = stake × multiplier × uptime — calculateWeightedScore() mirrors the on-chain formula exactly.

Quick start

import { createDepinClient, deriveNodeOperatorPda } from '@solinkify/depin';

// Requires env: NEXT_PUBLIC_RPC_URL, NEXT_PUBLIC_PROGRAM_ID, NEXT_PUBLIC_SINKY_MINT
const client = createDepinClient(provider, idl);   // AnchorProvider + program IDL

await client.registerNode({ stakeAmount: 100n * 1_000_000_000n, provider, idl }); // Bronze
const node = await client.fetchNodeOperator(wallet.publicKey);
const est  = await client.estimateReward(wallet.publicKey);

Fee routing (Jalur A/B)

computeFees() reproduces the on-chain split so dashboards and nodes can display exact expected amounts:

• Jalur A (direct): 99% seller · 0.9% treasury · 0.1% team
• Jalur B (via node): 99% seller · 0.375% relaying node · 0.375% epoch pool · 0.15% treasury · 0.1% team

Program

• Program id: A8qSJCS2uxxnEMdCcpjX2L8hUUMydoeCi5xq5qvzS22B (same on devnet & mainnet)
• PDAs: ["node_operator", operator], ["epoch_state", epoch_num]
