This page provides a comprehensive overview of Creditcoin's core network metrics and protocol parameters on Mainnet. Whether you're building on Creditcoin or integrating EVM-compatible applications, the data below offers additional insight into the performance, scalability, and technical structure of the blockchain.

Frontier version	Current: polkadot-v1.1.0-patch Planned: stable2409
EVM Compatibility	Yes
PolkadotSDK version	Current: release-polkadot-v1.1.0-patch Planned: polkadot-stable2409
Consensus	PoS
Block time	15s
Finality time	1-3 blocks
TPS - Substrate with full EVM use	~350 tps *
TPS - Substrate with no EVM use	~1400 tps *
TPS - ERC20 Transfers filled blocks	100 tps **
TPS - Simple eth transfers filled blocks	238 tps **
On-Chain Data Size	~50g as of May 2025
Supported EIPs	EIP-20 (ERC-20) EIP-721 (NFTs) EIP-1155 (ERC-1155)
BLOCK_GAS_LIMIT	75_000_000
Epoch	2880 blocks
Era	2 epochs
Base gas price	0.5 gwei
Elasticity	125_000 lower() 0 ideal() 500_000 upper() 1_000_000
Peak Observed EVM volume	~375k transactions in a day
Peak Observed Substrate volume	~400k extrinsics in a day
Substrate extrinsics fee	0.015932248 CTC for basic balance transfer
Substrate large data input fee per megabyte	110 CTC
EVM Transaction fee	Varies based on gas price, which varies based on % fill of recent blocks Formula Current gas price in wei * (estimated native transfer gas unit) / (decimals) Example with base fee for a simple transfer, assuming base gas price of 0.5 gwei 500000000*21000/(10^18) = 0.0000105 CTC

* May vary depending on factors such as other concurrent volume, type of transactions and extrinsics.

** Capacity calculated based on BLOCK_GAS_LIMIT, which can be increased to a desired value.
