EVM Layer 1
Kaia is an EVM-compatible Layer 1 network with account-based state, native transaction types and smart-contract execution.
Native KAIA belongs to protocol account state and pays fees; contract-token balances belong to token-contract storage.
Kaia tracks account-based state containing balances, nonces, keys, contract code and contract storage.
Each Kaia account maps an address to state that changes when a valid transaction executes.
Externally controlled accounts authorize transactions with registered account keys.
Smart-contract accounts contain deployed code and execute when called.
A sender nonce orders transactions and prevents the same signed transaction from being applied repeatedly.
An account balance records native KAIA available for transfers and fees.
The Kaia Virtual Machine executes EVM-compatible bytecode under network gas rules.
Contracts maintain persistent state after successful execution and block commitment.
One KAIA equals 1,000,000,000 Gkei or 1,000,000,000,000,000,000 kei.
Wallets display KAIA, gas prices are commonly expressed in Gkei, and raw transaction values use integer kei.
Kaia meters computation in gas and charges the resulting execution fee in native KAIA, with support for network-defined base and priority fee fields.
KAIA
Gas measures computation and storage work requested by a transaction.
The gas limit caps the work a transaction may consume.
Gas used records the work consumed by execution.
The network sets a base fee per gas that adjusts with block usage.
A priority fee can be supplied by compatible transaction types.
The transaction fee equals gas used multiplied by the effective gas price and is paid in KAIA.
A Kaia transaction is created, authorized, validated, propagated, executed, included in a block and finalized by BFT consensus.
Kaia executes EVM-compatible smart contracts while also supporting Kaia-specific transaction and account features.
Contract accounts contain deployed bytecode and have no private signing key.
Compiled EVM-compatible bytecode executes in the Kaia Virtual Machine.
Contracts read and update persistent storage after successful execution.
Calls can transfer native KAIA and pass encoded input to contract functions.
Token contracts maintain balances and allowances independently from native KAIA.
Native KAIA pays protocol gas; contract-token balances cannot automatically replace KAIA as the fee asset.
Kaia uses an optimized Istanbul BFT process to validate each proposed block and provide immediate finality after committee agreement.
Kaia uses an optimized Istanbul BFT mechanism with a governance-selected council and a committee selected for each block.
Consensus nodes operated by council members propose, validate and vote on blocks according to the active committee rules.
A selected consensus node proposes a block for the committee to validate and vote on.
When the required committee agreement is reached, the block is committed with immediate BFT finality rather than probabilistic confirmation depth.
Applications should verify the node-reported block and receipt state and handle RPC delays instead of treating a broadcast transaction as finalized.

A familiar KAIA ticker can refer to a legacy representation, a current asset or an unsupported migration route.
CoinGecko USD and Binance Spot KAIA/USDT are separate datasets. Wallet and application support for Kaia-specific transaction types can vary.
For Kaia, the practical sequence is Identify legacy asset, Verify current identity, Check route, Complete action, Confirm balance. Confirm the official destination and current network, then inspect the final balance, position, receipt or documented exit state that actually completes the task: Understand Kaia token migration and make safer usage and transaction decisions for Kaia.
Official transition documentation describes KAIA as the renamed successor of KLAY after the Kaia integration.
Gas fees are calculated from gas used and the effective gas price, then paid in native KAIA.
Kei is the smallest KAIA unit and Gkei equals one billion kei.
A selected committee of consensus nodes validates and agrees on each block through optimized Istanbul BFT, providing immediate finality after consensus.
Kaia (KAIA) pays the applicable network fee. Verify the selected network before signing because a later approval, bridge, claim or exit can require another transaction.
