DIDComm v2.1 Mediator is a secure message routing server that enables developers to build decentralised communication systems without managing complex peer-to-peer infrastructure. Using Decentralised Identifiers (DIDs) and the DIDComm v2.1 protocol, it ensures encrypted message exchange with confidentiality, integrity, and trust.
Overview
DIDComm v2.1 Mediator is a server that facilitates secure message exchange between parties in decentralised systems. Acting as a secure message router, it allows recipients to fetch messages addressed to their DID while maintaining end-to-end encryption.
Built using the DIDComm v2.1 messaging protocol and Decentralised Identifiers (DIDs), the mediator enables secure, privacy-preserving digital interactions. The protocol utilises public key cryptography to ensure message confidentiality, integrity, and authenticity, thereby establishing trust between senders and receivers without intermediaries compromising the data.
Available on AWS Marketplace, the mediator deploys to your AWS Cloud instance, giving you control over your messaging infrastructure. This solution empowers developers and organisations to:
-
Implement secure and verifiable peer-to-peer messaging in decentralised systems
-
Ensure privacy-first communication across applications
-
Simplify integration of DIDComm v2.1 protocols with ready-to-use mediator services
-
Scale digital trust solutions without compromising on security or compliance
Whether you are building decentralised apps, trust ecosystems, or secure communication channels,
DIDComm v2.1 Mediator provides the foundation for trusted digital interactions.
Highlights
- DIDComm Powered: Built on the DIDComm v2.1 protocol, ensuring interoperability with decentralised ecosystems.
- Trust and Authenticity: Every message is cryptographically signed and verifiable, eliminating risks of tampering or impersonation.
- Privacy-Preserving: End-to-end encrypted communication with public key cryptography, ensuring messages are only readable by intended recipients.

CloudFormation Template (CFT)
AWS CloudFormation templates are JSON or YAML-formatted text files that simplify provisioning and management on AWS. The templates describe the service or application architecture you want to deploy, and AWS CloudFormation uses those templates to provision and configure the required services (such as Amazon EC2 instances or Amazon RDS DB instances). The deployed application and associated resources are called a "stack."

- AWS Secrets Manager: Grants permission to retrieve secrets containing Decentralised Identifier (DID) and JSON Web Token (JWT) secrets for authentication and DIDComm messaging.
- AWS Parameter Store: Grants permission to read configuration parameters essential for the operation of the DIDComm Mediator, such as mediator DID, DID document, and admin DID.
- Amazon CloudWatch: Permissions to create log groups/streams and write logs for observability.
- Amazon Route 53: Scoped access to manage DNS records within a specified hosted zone for subdomain configuration to host the DIDComm Mediator instance.
These permissions are defined in IAM policies attached to roles assumed by the products compute resources (e.g., ECS tasks) during runtime.
