As part of our Coordinated Vulnerability Disclosure Policy, we operate a bug bounty. See the policy for more details on submissions and rewards.

The following is a list of examples of the kinds of bugs we're most interested in for the Cosmos SDK. See here for vulnerabilities we are interested in for Tendermint, and lower-level libraries, e.g. IAVL.

Modules

  • x/staking
  • x/slashing
  • x/types
  • x/gov

We are interested in bugs in other modules, however the above are most likely to have significant vulnerabilities, due to the complexity / nuance involved

How we process Tx parameters

  • Integer operations on tx parameters, especially sdk.Int / sdk.Uint
  • Gas calculation & parameter choices
  • Tx signature verification (code in x/auth/ante.go)
  • Possible Node DoS vectors. (Perhaps due to Gas weighting / non constant timing)

Handling private keys

  • HD key derivation, local and Ledger, and all key-management functionality
  • Side-channel attack vectors with our implementations
    • e.g. key exfiltration based on time or memory-access patterns when decrypting privkey
