@@ -10,7 +10,7 @@ There are two circumstances that could lead to transaction malleability:
**Use the [tfFullyCanonicalSig flag](transaction-common-fields.html#global-flags)** to guarantee that a transaction is not malleable in this way. Although transactions [signed with Ed25519 keys](cryptographic-keys.html#signing-algorithms) are not vulnerable to this problem, **there is no downside** to using this flag on _all_ transactions.
2. The transaction is [multi-signed](multi-signing.html) and has more signatures than necessary. Even if the transaction originally did not have more signatures than necessary, it could be malleable if one of the authorized signers provides an additional signature.

Good operational security can protect against these problems. See [Mitigations for Multi-Signature Malleability](#mitigations-for-multi-signature-malleability) for guidelines.
