A Private Sandbox For SWSS ChainWhere Every Build Becomes Mainnet Ready
Access to SWSS Chain Testnet is gated to the SWSS DevHub community. Builders, validators and integration partners join DevHub, once approved you receive RPC credentials, faucet quota and SDK access to test $500M+ of protocol stack: Four Pillar Consensus, DEED-1 settlement, SCP-ZK v3.3.0 privacy and SWSS IVL v1.4.3 identity in a production identical environment.
Connect To SWSS Chain
Same protocol, same DEED-1 standard, same Sub Second finality target as Mainnet. Only the chain ID and economic settings differ.
Three Steps From DevHub Approval To First DEED
Access is invitation only. Once your DevHub application is approved, the path from credential issue to your first anchored DEED-1 record takes minutes, not days.
Join SWSS DevHub
Apply through the SWSS DevHub community. The Foundation reviews your project, validator profile or integration scope before issuing Testnet credentials.
Receive Credentials
Approved members receive scoped RPC keys, daily faucet quota and SDK access tied to their DevHub identity. No public endpoints, no anonymous drips.
Deploy And Anchor
Push contracts, anchor your first DEED-1 record and verify Sub Second finality directly inside SWSS Explorer using the same SDK you will ship to Mainnet.
Same RPC Surface As Mainnet
JSON-RPC, REST and WebSocket, every endpoint exposed on Mainnet is mirrored on the Testnet so your integration code ships unchanged.
\\# get latest block
curl -X POST https://testnet.swssrpc.swss.io \
-H "Content-Type: application/json" \
-d '{
"jsonrpc":"2.0",
"method":"eth_blockNumber",
"params":[],
"id":1
}'
# response
{
"jsonrpc": "2.0",
"id": 1,
"result": "0x1A2B3C" // block height
}
# fetch a DEED-1 record

→ Type 0x03 · IVL Registry v1.4.3 · Finality ✓What You Can Test End To End
The Testnet exposes the full SWSS Chain protocol stack. Every primitive is wired the same way it is on Mainnet.
DEED-1 Records
Anchor Type 0x03 SCP Transactions and Type 0x04 AI Agent records against the canonical DEED-1 standard.
IVL v1.4.3 Credentials
Issue and bind KYC, Registry, Custody and AML credentials through the Foundation Provider Registry.
SCP-ZK v3.3.0
Generate selective disclosure proofs against the Testnet nullifier registry, Audit Without Reveal works end to end.
Finality Certificates
Verify Sub Second Finality Certificates issued by SCP v3.2.1 four pillar consensus with threshold signing research enabled.
AI Agent Records
Exercise the Type 0x04 path, register agents, anchor their actions and verify their IVL bound authority.
Validator Rotation
Observe On Chain Validator Rotation across NodeX qualified and Foundation Anchored operators in real time.
Testnet vs Mainnet
Same protocol surface, different operational guarantees. Promote your build to Mainnet once your Testnet flows are stable.
A Testnet Built To Carry Production Load
Every counter below is read live from the Testnet explorer and RPC, and refreshes every thirty seconds. A value that cannot be reached renders as a dash rather than a number. The Testnet runs the same Four Pillar Consensus and the same Sub Second finality as Mainnet.
Ship With The Tools You Already Know
SWSS Chain Testnet speaks every major EVM dialect. Plug in your existing Hardhat, Foundry, viem or ethers project and start anchoring DEED-1 records without rewriting a line.
Hardhat
Drop the Testnet into hardhat.config.ts as a network entry. Deploy, trace and verify against the same RPC surface as Mainnet.
Foundry
forge create and cast call work out of the box. Use --rpc-url with the Testnet endpoint and your usual private key flow.
viem & ethers
Both clients connect through standard JSON-RPC. Reuse your existing wallet, signer and transaction patterns unchanged.
swss-cli
First class CLI for network management, faucet drips, DEED inspection and IVL credential issuance. Single binary, scripted friendly.
SWSS SDK
Typed SDK for DEED-1 anchoring, SCP-ZK proof generation and Type 0x04 AI Agent records. Ships with TypeScript and Rust bindings.
Indexer & Subgraphs
Index DEED events directly via the public indexer or run your own subgraph against the Testnet's WebSocket stream.
From First Drip To Mainnet Anchor
A clear, four step pipeline to take your build from a Testnet faucet drip to a verified Mainnet DEED. Every step uses the exact same protocol surface, nothing to rewrite when you cross the line.
Fund From Faucet
Claim tSWSS from the open faucet. Daily caps keep distribution fair and predictable for everyone.
Deploy & Anchor DEEDs
Push your contracts to Testnet and anchor Type 0x03 and Type 0x04 DEED-1 records end to end.
Stress, Trace, Verify
Run integration suites against the live indexer. Trace finality, verify ZK proofs and audit IVL flows.
Promote To Mainnet
Flip the network to Mainnet Chain ID 122605 (0x1DEED). Same code, same SDK calls, real settlement.
