Why oracles exist
Blockchains cannot automatically know off-chain facts such as market prices, weather or sports results. Oracles provide external data to smart contracts.
A lending protocol may need an asset price to calculate collateral value.
Learn how smart contracts receive external data, how protocols make decisions, and why voting power, multisigs and admin keys matter.

Price feeds may aggregate data from multiple sources or use specialized mechanisms to reduce manipulation.
If an attacker can influence a price feed or exploit thin liquidity used by the oracle, a protocol may misprice collateral or trades.
Governance is the process through which protocol decisions can be proposed and approved. It may involve token voting, delegates, councils or multisig signers.
Voting power may be based on token balances, delegated voting power, staking positions or other mechanisms.
A multisignature wallet requires multiple authorized signers to approve an action. This can reduce single-key risk.
Some protocols delay execution of sensitive governance decisions, giving users time to review or exit.
Protocols may retain emergency pause, upgrade or parameter-setting powers. These can be useful for incident response but introduce centralized control.
A proposal should be evaluated by its exact code changes, parameters, voting process and execution path—not just the title.
Identify oracle providers, admins, multisig signers, timelocks, upgrade paths, quorum and emergency powers.
Before moving money, connecting a wallet, trusting a claim or signing a transaction, slow down. Identify the exact asset, network, contract, source, permissions and risks.
