Constants

MultiversX uses some constants, which are specific to each chain (Mainnet, Testnet or Devnet). The updated values can be found at these sources:

Mainnet:

• https://github.com/multiversx/mx-chain-mainnet-config

Testnet:

• https://testnet-gateway.multiversx.com/network/config
• https://github.com/multiversx/mx-chain-testnet-config

Devnet:

• https://devnet-gateway.multiversx.com/network/config
• https://github.com/multiversx/mx-chain-devnet-config

important

Each transaction requires a chainID field that represents the network's identifier. It adds protection so that transactions cannot be replayed from a network to another. The values are:

• Mainnet: 1
• Testnet: T
• Devnet: D

At the time of writing, the most used constants values for mainnet were:

• Round duration: 6 seconds
• Epoch duration: 14400 rounds, 24 hours
• Min gas price: 1000000000
• Min gas limit: 50000
• Chain ID: 1 (T for Testnet, D for Devnet)
• Min deposit for the creation of a system delegation smart contract: 1250 EGLD
• Min deposit for a validator: 2500 EGLD
• Number of eligible validators per shard: 400 validators
• Number of eligible validators per metachain: 400 validators
• Max number of active (eligible + waiting) validators: 3200 validators
• Consensus group size on shard: 63 validators
• Consensus group size on metachain: 400 validators
• Min deposit for staking provider: 1 EGLD
• Min deposit for legacy delegation: 10 EGLD
• Unbonding duration for legacy delegation: 144000 blocks
• Unbonding duration for staking providers: 10 epochs
• EGLD denomination: 18
