Wire Alchemy into application code (server, backend, dApp, script) using a standard API key. Preferred app-integration path for normal server/backend usage. Covers EVM JSON-RPC, Token API, NFT API, Transfers API, Prices API, Portfolio API, Simulation, Webhooks, Solana RPC, Solana DAS, Solana Yellowstone gRPC, Sui gRPC, Wallets/Account Kit, and operational topics. Requires `$ALCHEMY_API_KEY`. For live agent work in this session (querying, admin, local automation), use `alchemy-cli` (preferred) or
Migrate a subgraph from The Graph to Goldsky as a drop-in replacement — no code changes required. Use this skill when the user wants to move, switch, port, or migrate a subgraph off The Graph (hosted service, Subgraph Studio, or the decentralized network) onto Goldsky, or when a subgraph endpoint they relied on (e.g. The Graph hosted service) was sunset. Triggers on: 'migrate from The Graph', 'move my subgraph to Goldsky', 'switch off The Graph', 'redeploy a TheGraph subgraph', 'my subgraph endp
Diagnose and fix broken Goldsky Subgraphs. Use this skill whenever a user has a subgraph that is failing, stalled, stuck syncing, not indexing, auto-paused, returning errors, or won't deploy. Triggers on: 'subgraph stopped syncing', 'subgraph stuck at block', 'subgraph stalled', 'subgraph failed to deploy', 'indexing error', 'SubgraphSyncingFailure', 'unexpected null in handler', 'no network found', 'deployment already exists', 'subgraph not returning data', 'subgraph endpoint 404', 'reached the
Build, author, and deploy Goldsky Subgraphs — hosted GraphQL APIs over onchain data. Use when the user wants to create, scaffold, write, or deploy a subgraph; design a schema/entities; write or fix AssemblyScript mapping handlers; configure subgraph.yaml (handlers, templates, instant/no-code from ABI); set up GraphQL endpoints, tags, or webhooks; optimize a slow subgraph (eth_calls, immutable entities); or pause/resume a subgraph. Triggers on: 'build/deploy/scaffold a subgraph', 'write a mapping
Diagnose an existing Goldsky Compose app with failing tasks, crashloops, missed events, cron not firing, HTTP 500s, wallet or gas sponsorship failures, missing secrets, bundler errors, manifest validation failures, or esbuild failures. Use when an app is named alongside a problem involving goldsky compose, including 'No bundler provider available', named wallets without a private key in local dev, and 'Transaction Receipt failed with status'. Load /compose first; inspect status, logs, secrets, a
Always load this skill whenever the conversation is about Goldsky Compose (the offchain-to-onchain TypeScript framework for oracles, keepers, circuit breakers, and cross-chain automation) — no matter what the user wants to do with it. That includes: asking what Compose is, its docs, pricing, functionality, or limits; building, deploying, or iterating on an app; wiring cron / HTTP / onchain-event triggers, smart wallets, gas sponsorship, secrets, or collections; deploying a worked example (bitcoi
Configure and troubleshoot Goldsky Edge, Goldsky's managed EVM RPC endpoint service. Use for Edge RPC, Goldsky RPC endpoints, edge.goldsky.com, slow eth_getLogs, rate limits, hedged requests, flashblocks, HyperEVM system transactions, x402 pay-per-request RPC, pricing, the Edge dashboard, gs_edge_ keys, rpc-edge, and errors -32005/-32012/-32014/-32015/-32016. Covers resilient low-latency EVM endpoints and provider comparisons. For self-hosted eRPC configuration, consult docs.erpc.cloud/llms.txt.
Trace cryptocurrency addresses and transactions on public blockchains using block explorers including Etherscan, Blockchair, mempool.space and Blockscout. Covers common-input clustering, ENS resolution, exchange deposit addresses, mixers, CoinJoin, Tornado-style pools, cross-chain bridges, and OFAC sanctions screening. Use when following a Bitcoin or Ethereum wallet, investigating where a ransom or scam payment went, or checking an address against sanctions listings. Applies to ransomware incide
Smart contract vulnerability playbook. Use when auditing Solidity/EVM contracts for reentrancy, integer overflow, access control, delegatecall, flash loan, signature replay, and MEV-related attack patterns.
DeFi attack pattern playbook. Use when analyzing flash loan attacks, price oracle manipulation, MEV sandwich attacks, governance exploits, bridge vulnerabilities, and token standard edge cases in decentralized finance protocols.
Use when a request involves Ethereum, the EVM, or blockchain systems. Applies to building, auditing, deploying, or interacting with smart contracts, dApps, wallets, or DeFi protocols. Covers Solidity development, contract addresses, token standards (ERC-20, ERC-721, ERC-4626, etc.), Layer 2 networks (Base, Arbitrum, Optimism, zkSync, Polygon), and integrations with DeFi protocols such as Uniswap, Aave, and Curve. Includes topics such as gas costs, contract decimals, oracle safety, reentrancy, ME
Use when an agent hits HTTP 402 / payment-required, or the user mentions x402, x402Version, X-PAYMENT, PAYMENT-REQUIRED, PAYMENT-SIGNATURE, WWW-Authenticate: Payment, permit2, upto, metered billing, a payment channel / voucher / session, channelId / channel_id, opening / closing / topping up / settling / refunding a channel, a paymentId or a2a_ link, or creating / checking a payment link. Covers x402 (exact, exact+Permit2, upto, aggr_deferred), MPP (charge / session), and a2a-pay paymentId flows
