Kraken
Framework category: on-ramp
Long-running US exchange with a broad asset menu and Wyoming SPDI charter; common second on-ramp.
Primary use
Backup on-ramp. Many readers use Kraken specifically as redundancy to Coinbase so a single account freeze does not stop money movement.
Redundancy role
On-ramp peer. Functionally equivalent role to Coinbase. Spread fiat balances thin across both.
Historical yield range
Flexible staking has historically been quoted up to roughly 10% APY and bonded staking up to roughly 21% APY, with most assets much lower (for example BTC near 0.02% on flexible). Rates change weekly and vary by asset; verify current rates before deploying.
Integration notes
Regulatory: FinCEN MSB, SEC-registered broker-dealer (FINRA/SIPC), SEC-registered investment adviser, Wyoming SPDI. Fees: instant trades 1%, custom orders 1.5%, Kraken Pro spot 0.25% maker / 0.40% taker at entry tier. Flexible staking unstakes instantly; bonded staking locks for a fixed term. Weekly staking payouts.
Watch-outs
Crypto volatility, staking slashing/hacks with no guaranteed rewards, spread costs on instant trades, withdrawal fees on some assets, and jurisdictional restrictions.
