How does Kadena's Chainweb scale PoW?

Chainweb braids 20 parallel blockchains that mine simultaneously and reference each other's block hashes, creating a shared security pool while multiplying throughput linearly with chain count.

Can I swap KDA without KYC?

Yes. SyntheticSwap supports KDA swaps with no registration or identity verification.

Pact is Kadena's smart contract language designed to be human-readable (non-Turing-complete) with built-in formal verification, making it significantly safer than Solidity for writing smart contracts.

Is Kadena still mineable?

Yes. Kadena uses Proof of Work and can be mined with GPUs. The 20-chain Chainweb architecture means miners can mine any chain in the network.

What are the gas fees on Kadena?

Kadena gas fees are extremely low — fractions of a cent — making it practical for microtransactions and high-frequency DeFi operations.

About Kadena

Kadena (KDA) is a public Proof-of-Work blockchain that claims to solve the blockchain trilemma through its unique Chainweb architecture — a braided multi-chain design where multiple chains process transactions in parallel and share security. Founded by Stuart Popejoy and Will Martino, former JPMorgan blockchain developers who built the first blockchain for the US Federal Reserve, Kadena launched its mainnet in 2020 with 10 chains and later scaled to 20. Kadena also created Pact, a human-readable smart contract language with formal verification, designed to make contracts more secure and auditable.

How to Swap KDA

Exchanging Kadena (KDA) on SyntheticSwap requires no account creation or identity documents. Open SyntheticSwap, choose KDA as your source or target coin, provide your destination wallet address, and review the floating rate displayed. After sending KDA from your personal wallet to the deposit address, the swap processes automatically and your chosen asset is delivered directly to your wallet. SyntheticSwap never holds your funds at any point during the process.

How to Store KDA

KDA is stored in Kadena-compatible wallets. Chainweaver is the official desktop wallet with full dApp support. Koala Wallet is a popular mobile/web option. Ledger hardware wallets support KDA. When storing KDA, note that Kadena uses account names rather than addresses — typically starting with 'k:' followed by your public key.
