Weekly sync from merged docs changes (week of 2026-05-06 → 2026-05-13).

Docs PRs covered

Material changes:

• #1173 — Add getTransactionsForAddress Solana API spec (new JSON-RPC method)
• #1266 — Base Flashblocks subscriptions switched to event-based pricing
• #1281 — Docs for 5 new Bitcoin-ecosystem chains (BCH mainnet/testnet, LTC mainnet/testnet, DOGE mainnet) + UTXO REST API
• #1282 — Alchemy CLI command structure rewrite (evm, solana, xchain, wallet, app, webhook groups)
• #1285 — v5 wallet API examples switched from transactionHash to call ID for tracking sends
• #1287 — Solana DAS Try It defaults fixed for getTokenAccounts and searchAssets (phantom params removed, real param set documented)

Non-material (skipped):

• #1283 — wallet-api spec zod regen (schema tightening, no user-facing API surface change)
• #1284 — weekly node-upgrade changelog
• #1291, #1292, #1295 — UTXO migration guide / overview page / title rename (content positioning, not API surface)

Skills files updated

• skills/alchemy-cli/SKILL.md — full command-tree refresh for PR #1282. Updated every task-to-command row (alchemy balance → alchemy evm data balance, alchemy tx → alchemy evm tx, alchemy webhooks → alchemy webhook, alchemy apps → alchemy app, …). Added EVM wallet-signed transactions, swaps, Solana sends/delegate/program, cross-chain bridge, and the new wallet connect/use/status flow. Replaced setup status with doctor/config status. Dropped --access-key (now derived from auth login).
• skills/alchemy-api/references/operational-supported-networks.md — added bitcoincash-mainnet, bitcoincash-testnet, litecoin-mainnet, litecoin-testnet, dogecoin-mainnet, bitcoin-testnet4 to the Data API network list. Added a "Recently Added" section explaining the UTXO REST API surface across all 7 UTXO networks.
• skills/alchemy-api/references/solana-das-api.md — rewrote searchAssets params section to mark ownerAddress required, add tokenType (with case-sensitivity note), document delegate (not delegateAddress), call out interface/tokenType mutual exclusion and pagination strategy rules. Added a brand new getTokenAccounts section since it's now part of the DAS spec.
• skills/alchemy-api/references/solana-rpc.md — added getTransactionsForAddress method section with full param table and the rationale for preferring it over getSignaturesForAddress + per-signature getTransaction.
• skills/alchemy-api/references/wallets-wallet-apis.md — added "Tracking Sends: Call ID, Not Transaction Hash" subsection covering the v5 SDK call-ID-first pattern.
• skills/alchemy-api/references/operational-rate-limits-and-compute-units.md — added Webhooks/Subscriptions pricing section noting the Flashblocks event-based pricing exception (40 CU / 60 CU) vs the default 0.04 CU / byte.

Material changes

• New chains: Bitcoin Cash mainnet+testnet, Litecoin mainnet+testnet, Dogecoin mainnet. All share Bitcoin Core JSON-RPC method set and the new UTXO REST API (Trezor Blockbook-derived).
• New REST surface: UTXO REST API exposed across 7 UTXO networks at https://{network}.g.alchemy.com/v2/{apiKey}/api/v2/....
• New JSON-RPC method: Solana getTransactionsForAddress returns transactions for an address with status/slot/blockTime/tokenAccounts filters and pagination.
• CLI surface rewrite: every command moved under chain/product groups (evm, solana, xchain, wallet, app, webhook). Added wallet-signed sends, swaps, bridges, Solana sends/delegate/program.
• DAS param corrections: getTokenAccounts and searchAssets had phantom params removed (programId, commitment, dataSlice, encoding, delegateAddress, mutable) and required fields tightened (ownerAddress required on both).
• Wallet API pattern: tracking sends via call ID, not receipts[0].transactionHash.
• Pricing: Base Flashblocks subscriptions (newFlashblockTransactions, newFlashblocks) now event-priced (40 / 60 CU per event) instead of byte-priced.
