BLEEP Connect

Four-Tier
Cross-Chain Bridge.

No permanently privileged operator. No trusted multisig key set. From 200ms instant relay to 7-day social consensus — four security tiers, each backed by a different trust model. ETH · BSC · SOL · COSMOS · DOT.

BLEEP Connect routes cross-chain intents through the appropriate tier automatically. No configuration required from the user. The bridge selects the tier based on transfer size, speed preference, and destination chain state.

Automatic Tier Selection

The Right Tier for
Every Transfer.

Scenario Recommended Tier Rationale
DeFi swap · <$1,000 Tier 4 — Instant Speed prioritised; economic bond sufficient for small amount
Regular cross-chain transfer · $1K–$100K Tier 3 — ZK Proof Cryptographic certainty without hours of delay
Large institutional transfer · >$100K Tier 2 — Full-Node Full chain-state verification; no economic risk model
Protocol upgrade / treasury spend Tier 1 — Social Maximum consensus; governance participation mandatory
Privacy-sensitive amount Tier 3 — ZK Proof STARK proof reveals nothing beyond validity of transfer
Tier 3 — ZK Proof Flow
