Evaluate a multisig wallet
Compare signer thresholds, recovery and modules that can bypass ordinary approvals.

Start with: account abstraction, approvals.
A multisig requires a defined number of signers to authorize an action. A two-of-three arrangement, for example, needs two of three owners. It can reduce dependence on one key, but its safety depends on how independently those keys are controlled.
Compare the actual authority
Record:
- owners and signing threshold;
- supported networks and account type;
- how owners and thresholds can change;
- recovery and signer-replacement arrangements;
- modules, guards, delegates and spending limits.
Additional components may have powers beyond the ordinary signer workflow.
Bitcoin multisig uses spending conditions over outputs. EVM smart-account multisigs use contract logic. Backups, transaction coordination and recovery differ; a guide for one does not automatically apply to the other.
A realistic test
With a small test account, prepare a transfer, verify its full effects independently, obtain the required approvals and execute. Then test losing one signer according to your recovery plan. Do not delete the only working backup to conduct a test.
If all three signers are stored in the same password manager on the same laptop, a common compromise can defeat the intended separation. Independence includes people, devices, storage and the process used to verify requests.
note — A two-of-three threshold describes authorization. It does not prove that the three signers are operationally independent.
Operational tradeoffs
More signers can make urgent actions slower. Too low a threshold concentrates power; too high a threshold can lock out the group. Document how replacements, disputes and unavailable signers are handled.
A multisig protects authorization, not the economics of a malicious contract that enough signers approve. Review every transaction's destination, value, call data and permission changes rather than approving a request because another signer already did.
