Backing models differ sharply: fully reserved fiat-backed tokens, overcollateralised crypto-backed tokens, and algorithmic designs with a poor survival record. The risks that matter are issuer and reserve risk, freeze capability, chain-specific bridged versions, and liquidity depth on the venue you use.

Related concepts

The vocabulary this page depends on.

  • DeFi

    DeFi is financial infrastructure built as open smart contracts — lending, trading, staking and derivatives that anyone can use or compose.

  • DEX

    A DEX is an exchange implemented as smart contracts, where trades settle on-chain from your own wallet instead of an internal exchange ledger.

  • Crypto Risk Management

    Risk management in crypto is position sizing plus custody hygiene: deciding what you can lose per trade and what a single compromise can reach.

  • Crypto Automation

    Crypto automation is rule-based execution of monitoring, alerting and recurring on-chain actions, so decisions are made once and applied consistently.

  • Track Stablecoins

    Monitoring stablecoin balances by chain and version surfaced $12k stranded in a bridged token with almost no exit liquidity.

  • Monitor A Crypto Portfolio

    Aggregating six addresses across three chains revealed that a portfolio believed to hold 14 positions actually held one concentrated bet.

Comparisons & alternatives

Pick between the options.

  • Stablecoins vs Bank Transfers

    Stablecoin transfers settle in minutes on public rails; bank transfers settle slower but come with reversibility and regulated protection.

  • DeFi vs Traditional Finance

    DeFi offers open access, composability and transparent rules; traditional finance offers legal recourse, insurance and stability.

  • CEX vs DEX

    Centralised exchanges optimise for liquidity, fiat access and convenience; DEXs optimise for custody, permissionless listing and on-chain transparency.

  • Custodial vs Self-Custody

    Custody choice is a swap between counterparty risk you cannot control and operational risk you can.
