--- name: Polkadot description: Assist with Polkadot DOT transactions, staking, parachains, and cross-chain transfers. metadata: {"clawdbot":{"emoji":"⚪","os":["linux","darwin","win32"]}} --- ## Network Architecture - Relay Chain is the main chain — coordinates security and consensus - Parachains are independent chains — connected to Relay Chain for security - DOT is the native token — used for staking, governance, and parachain bonds - Kusama is the canary network — experimental, real value, faster upgrades ## Address Format - Addresses are different per network — same seed gives different addresses on Polkadot vs Kusama - Polkadot addresses start with "1" — Kusama starts with capital letters - SS58 format — different from Ethereum's hex addresses - One seed for all Substrate chains — but displayed address differs per chain ## DOT Token - Redenominated 100x in 2020 — old 1 DOT = new 100 DOT - 10 decimals (planck is smallest unit) — different from 18 decimals on Ethereum - Existential deposit: 1 DOT minimum — accounts below this are reaped (deleted) - Locked DOT still counts for governance — can vote while staking ## Staking (Nomination) - Nominate up to 16 validators — your stake backs their validation - Minimum to earn rewards varies — currently around 250 DOT due to competition - 28-day unbonding period — funds locked during unstaking - Slashing risk exists — bad validators can lose portion of stake - Rewards claimed manually or auto-compound — depends on wallet ## Staking Pools - Minimum 1 DOT to join pool — lower barrier than direct nomination - Pool operator manages validator selection — less control, more convenience - Rewards distributed by pool — minus pool commission - Same unbonding period applies — 28 days to unstake ## Governance - OpenGov system — proposals, referenda, voting - Conviction voting — lock tokens longer for more voting power - Anyone can submit proposals — DOT holders vote - Treasury funds ecosystem development — community-controlled spending ## Parachains - Parachain slots won via auctions — projects bid DOT - Crowdloans let users contribute DOT — locked for lease period (2 years) - Contributed DOT returned after lease — plus project tokens as reward - System parachains have permanent slots — Statemint, Bridge Hub ## Cross-Chain (XCM) - XCM is cross-consensus messaging — transfer assets between parachains - Teleport vs Reserve transfer — different trust models - Not all parachains support all assets — check compatibility - Fees paid in DOT or parachain token — depends on route ## Wallets - Polkadot.js is power-user wallet — full features, complex UI - Nova Wallet, Talisman — better UX for most users - Ledger support — via compatible wallets - SubWallet for mobile — good mobile experience ## Common Issues - "Existential deposit" error — balance would go below 1 DOT, add more or send all - Staking not earning — below minimum active stake threshold - Can't transfer while staking — must leave some unlocked for fees - Wrong network address — Kusama address won't work on Polkadot - Unbonding takes 28 days — patience required ## Transaction Characteristics - Transactions finalize in ~12 seconds — deterministic finality - Fees in DOT — relatively low, paid from transferable balance - Nonce-based like Ethereum — transactions processed in order - Tips for priority — optional, not usually needed ## Security - Seed phrase controls all Substrate chains — secure it carefully - Verify addresses match network — different display per chain - Check validator reputation before nominating — slashing affects you - Governance attacks possible — vote on important proposals
