What we build
Discuss Your ProjectERC827 Compatibility Review Services
Call-Target Analysis
Map which external actions a token operation can trigger.
Permission Review
Examine approval scope and unexpected call paths.
Replacement Design
Plan a clearer interface when legacy behaviour is unnecessary.
A familiar proposal number does not establish current suitability
ERC-827 is an older proposal for extending token operations with additional call behaviour. We treat it as a compatibility investigation, not a default choice for a new token. Existing contracts, authorisations and external targets are reviewed before recommending maintenance or replacement.
Implementation history
Pin deployed code rather than relying on a name.
External execution
Constrain targets and explain failure propagation.
Practical Use Cases
01
Legacy audits
Understand an inherited transfer-and-call integration.
02
Application repair
Remove unsupported assumptions from consuming code.
03
Contract transitions
Prepare a reconciled move to maintained interfaces.

ERC827 Compatibility Review FAQs
Should ERC-827 be chosen automatically for a new token?
No. Start from the current product requirement and evaluate maintained alternatives.
Can a proposal label identify deployed behaviour?
No. The actual contract revision and integrations must be inspected.
