ETH RPC Cache Layer

A simple http server to cache specific eth rpc requests in memory. Useful for massive repeatedly requests to ETH rpc endpoints. Multiple endpoints/chains can be configured to be cached.

Usage (with docker)

docker run \
  -d \
  -p 8124:8124 \
  -v ./data/:/data/ \
  -e DATA_PERSISTENCE=1 \
  -e ENDPOINTS="eth-chain=https://rpc.ankr.com/eth,bsc-chain=https://rpc.ankr.com/bsc" \
  --name cached-eth-rpc \
  ghcr.io/tonyke-bot/cached-eth-rpc

Usage

With

cargo run --release -- \
  --port 8124 \
  --endpoint "eth-chain=https://rpc.ankr.com/eth" \
  --endpoint "bsc-chain=https://rpc.ankr.com/bsc"

Following redirection will be made:

• http://localhost:8124/eth-chain -> https://rpc.ankr.com/eth
• http://localhost:8124/bsc-chain -> https://rpc.ankr.com/bsc

Supported methods

Mainly supported requests with determined block number. Other methods will be directly send to the configured ETH rpc endpoint.

• eth_call
• eth_chainId
• eth_getBalance
• eth_getBlockByNumber
• eth_getCode
• eth_getStorageAt
• eth_getTransactionByHash
• eth_getTransactionCount
• eth_getTransactionReceipt
• eth_getTransactionByBlockNumberAndIndex
• eth_getTransactionByBlockHashAndIndex
