Build trading and lending apps on Ink, the Ethereum layer 2 built by Kraken, with reliable HTTPS and WebSocket RPC.
Connect your application to Ink Mainnet over HTTPS and WebSocket. Read contract state, follow events, and submit signed transactions with familiar Ethereum tools.
Build Ink applications with archive state, execution traces, and predictable RPC capacity.
Run Ink indexers and application backends with unlimited requests within your selected RPS tier. Keep monthly RPC costs predictable as request volume grows.
Query historical contract state and backfill event logs for Ink indexers, accounting, and DeFi analytics.
Inspect Ink transaction execution, diagnose reverted calls, and investigate internal contract activity with debug APIs.
Read pool state, simulate calls, and submit signed swaps. Connect trading interfaces to Ink with ethers.js or viem.

サポート対象ネットワーク上でChainstack を利用しているチームからの顧客事例。
Chainstackの堅牢なインフラストラクチャにより、Web3環境を効果的に保護する当社の能力が大幅に向上しました。Chainstack Brave Walletのマルチチェーン機能とユーザー体験（UX）の向上において、極めて重要な役割を果たしてきました。「Unlimited」Node の定額料金モデルにより、コストの予測可能性が確保され、パフォーマンスも極めて安定しています。インシデントは週1回からゼロにまで減りました。Chainstack との連携により、Web3セキュリティにおける複雑な課題に取り組む一方で、インフラコストを70%以上削減することができました。
Follow new blocks and contract logs over WebSocket, then backfill event history over HTTPS. Build trading, lending, and wallet workflows around confirmed receipts and the state your application needs.

Ink RPC connects applications to Ink through JSON-RPC over HTTPS or WebSocket. Read balances and contract state, retrieve event logs, and submit signed transactions. See Ink developer documentation.
Create a free Chainstack account, create a project, and deploy an Ink Global Node on mainnet. Copy your HTTPS or WebSocket URL from Access and credentials. The Developer plan includes 3 million request units per month, up to 25 requests per second, and one node. No credit card is required.
メインネットのHTTPS URLは以下の通りです。 https://ink-mainnet.core.chainstack.com/YOUR_ENDPOINT_ID.node から認証済みの URL 全体をコピーし、例示されているエンドポイント ID を置き換えてください。詳しくは、 Ink tooling guide.
Ink Mainnet uses chain ID 57073 (0xdef1)。ガス通貨はETHです。ウォレットの設定やトランザクションの署名を行う際は、ご使用のエンドポイントに対応するチェーンIDを使用してください。詳しくは、 公式ネットワークの詳細.
Chainstack currently serves Ink Mainnet. Ink Sepolia is a separate public test network, but it is not currently offered in Chainstack’s deployment matrix. Do not point a mainnet application at a testnet RPC URL. Check supported networks.
Yes. Configure your wallet or library with your Ink RPC URL and chain ID. Use HTTPS for JSON-RPC requests and your WSS URL for supported subscriptions such as new blocks and contract logs. Follow the Ink tooling guide.
Chainstack supports Ink archive access on mainnet. Archive state supports historical contract reads and analytics. Archive requests are billed at 2 request units; the exact classification depends on the method and block age. Archive access is available from Growth. See request-unit rules and supported network modes.
Use an Ink node with debug and trace APIs enabled on a paid plan. Ink runs op-reth and exposes debug_* そして trace_*; tracer availability depends on the client. See Ink debug requirements.
Ink does not expose a public pending-transaction feed like Ethereum’s. Use transaction receipts, new-block subscriptions, and contract logs to follow confirmed activity. Ink also publishes a separate Subblocks stream for preconfirmations; it is not the same as a pending-transaction subscription. See the Ink RPC documentation.
電話 eth_getLogs 範囲が限定されたブロック範囲と、必要なイベントトピックを指定します。ERC-20の転送では、標準の Transfer(address,address,uint256) イベントシグネチャ。特定のトークンの契約アドレスでフィルタリングし、大規模なバックフィルについてはページネーションを行います。このリクエストでは標準の Ethereum- 互換性のあるイベントログパラメータ.
まずは無料の「Developer」プランから始めましょう。有料プランは、年間契約の場合、月額40ドルからご利用いただけます。「Node 」の無制限プランでは、「Growth」プランの定額制リクエスト容量が追加されます。「Nodes 」の専用プランをご利用いただくには、「Pro」プラン以上が必要で、インフラストラクチャの料金は別途請求されます。現在の各プランの機能を比較してください。
No. Ink is Kraken’s EVM-compatible Ethereum Layer 2. The ink! language belongs to the Polkadot and Substrate smart-contract ecosystem. For Ink network configuration and Ethereum development tools, use the Ink tooling guide.
