2 credits per API call + additional credits based on the size of the stored data and the type of the blockchain
Store data on the blockchain.
The total cost of a transaction on Ethereum (in credits) depends on the size of the data. The data is stored as a string in the hexadecimal format, and the maximum size of the data is approximately 130 kB on the mainnet and 30 kB on testnet. Every 5 characters cost 1 credit.
Therefore, one API call with 1 kB of data (1024 characters) would cost 205 credits.
This API is supported for the following blockchains:
- BNB Smart Chain
- Celo
- Elrond
- Ethereum (only the mainnet or the Sepolia testnet)
- Harmony
- Klaytn
- Polygon
- XDC
