Grid Stablecoin Accounts deliver enterprise-grade security without compromising on user experience or developer experience. Built on the fully open-source Squads Protocol, Grid provides a unique non-custodial architecture that virtually eliminates vendor lock-in while maintaining the simplicity and reliability that modern applications require.

​
Fault Tolerance and Redundancy

Grid’s non-custodial architecture provides unprecedented fault tolerance and redundancy:

Open Source Foundation

Built on Squads Protocol, fully open source and auditable. No proprietary custody mechanisms or hidden dependencies.

Easy Migration

Simply prompt users to update signing keys on their accounts. No manual backups.

Implementation Flexibility

You can implement Squads Protocol directly without Grid APIs if needed in the future.

True Ownership

Users control their accounts directly through the blockchain. Grid provides tooling, not custody.

How Grid Works: Automated Multi-KMS Architecture

Protection Against Catastrophic Scenarios When you deploy a Grid Stablecoin Account, keys are automatically created with your user’s email address and deployed across multiple KMS providers. This protects against vendor business failures, security breaches, key loss, or extended service unavailability.
1

Automatic Multi-KMS Deployment

Every Grid account is deployed with 2 signer keys (1 of 2 threshold) across different KMS providers using the user’s email as the identifier.
2

Vendor Risk Mitigation

If a KMS provider goes out of business, loses keys, or becomes permanently unavailable, the backup key with another provider maintains full account access.
3

Seamless Key Rotation

Any compromised or lost key can be rotated without changing the user’s wallet address, since keys are purely for signing operations.
4

Business Continuity

Your application remains operational even during extended vendor outages or permanent provider changes.

​
The Key Management Challenge

Building Complete Solutions Key management services provide excellent security for individual keys, but building fault-tolerant applications requires additional layers of redundancy and user ownership. Grid complements KMS providers by adding the missing pieces for complete custody solutions.
When building robust applications, teams often need to address critical risk scenarios: Key Challenges:
  • Vendor business failure: What happens if a KMS provider goes out of business?
  • Permanent key loss: How to maintain access if keys are irretrievably lost?
  • Security breaches: Quick key rotation to mitigate risks during provider compromises
  • Extended outages: Business continuity during prolonged service unavailability
  • Migration constraints: Avoiding architectural lock-in that limits future flexibility

​
How Grid Completes the Solution

Complementary Architecture Grid doesn’t replace key management services – it orchestrates them. By combining multiple KMS providers with non-custodial account architecture, Grid delivers the complete custody, security, and user experience solution that applications need.

​
Enterprise-Grade Vendor Selection

Grid’s fault tolerance relies on strategic partnerships with verified key management service providers: KMS Partner Criteria:
  • Security certifications: SOC 2 Type II, ISO 27001 compliance
  • Proven reliability: Track record of uptime and security
