Description

Remove the deprecated BlockCypher network adapter and the deprecated Alchemy RPC server endpoints, which were triggering irrelevant errors.

• BlockCypher was a broadcast-only fallback adapter for Ethereum. Its adapter (BlockcypherAdapter), the case 'blockcypher' in makeNetworkAdapter, the BlockcypherAdapterConfig union member, the 'blockcypher' value in asNetworkAdaptorConfigType, the blockcypherApiKey init option, and the { type: 'blockcypher', ... } config in ethereumInfo are all removed. ETH broadcast continues to work through the remaining RPC adapter.
• Alchemy RPC endpoints (eth-mainnet.g.alchemy.com in ethereumInfo, eth-holesky.g.alchemy.com in holeskyInfo) are removed from the RPC server lists. The Ethereum mainnet RPC list keeps 9 other servers; sync and broadcast are unaffected.
• The now-unused alchemyApiKey init option (Ethereum and Solana) and the commented-out Solana Alchemy endpoint are also removed. Edge cleaners silently strip unknown keys, so the gui passing these keys is harmless.

The matching test fixture (currencyInfoFixture) is updated to drop the BlockCypher adapter entry so the discriminated-union exhaustiveness holds.

Testing

• tsc clean on the changed files (the pre-existing repo-wide tsc errors in monero/bip32/walletSettings come from local node_modules drift and are identical on master).
• Ethereum network unit tests pass (13/13), including the processEvmScanTransaction cases that build the engine adapters from the updated fixture.
• iOS sim (edge-funds): built the gui with the modified plugin linked and opened the Ethereum mainnet wallet "My Ether 2". Balance synced (0.000000302695953 ETH) and transaction history loaded (Swap Funds, Received Ethereum) via the remaining RPC/evmscan adapters, confirming ETH functionality after the removal. Proof screenshots attached.

Note

Low Risk
Provider and config cleanup only; sync and broadcast rely on remaining adapters, with no auth or data-model changes.

Overview
Cleans up deprecated Ethereum network providers that were still configured but only produced noise in logs.

The BlockCypher broadcast-only adapter is removed end-to-end (BlockcypherAdapter, 'blockcypher' adapter type, blockcypherApiKey, and the mainnet BlockCypher config entry). ETH broadcast continues through the existing RPC (and other) adapters.

Alchemy RPC URLs are dropped from Ethereum mainnet and Holesky server lists, and alchemyApiKey is removed from Ethereum and Solana init-option cleaners (plus a commented Solana Alchemy archival URL). The Ethereum test currencyInfoFixture is updated so adapter config types stay exhaustive.

CHANGELOG records the change under Unreleased.
