Release notes for builders on Fusion. This page is dedicated to updates about releases of the Python SDK and the fusion CLI, improvements to the MCP server and the website, new features, and new fuses, factories and contract deployments.
All
v4.2.0
A Fuse Whitelist check in validation and preflight, Compound V3 lending health and the Compound V3 Institutional USDC market on Ethereum.
IPOR Alpha status in the vault API
The API docs and the OpenAPI description cover the IPOR Alpha status fields of the vault list, and the docs explain how to reuse whitelisted fuses.
v10 and Compound V3 Institutional USDC on Ethereum
Fusion Factory v10 on Ethereum, and fuses for the Compound V3 Institutional USDC market: supply, borrow, value the position and claim rewards.
v4.1.0
A strict address parser, HyperCore pre-hook wiring and order book reads, and the feeds behind Morpho oracles in the oracle mapping.
IPOR Fusion on Polygon
IPOR Fusion is deployed on Polygon: a Fusion Factory and fuses for Aave V3, Compound V3, Morpho, ERC-4626 vaults, Merkl rewards and swaps.
Docs samples for Python SDK 4.0
The Python samples in the Fusion docs use ipor-fusion 4.0, and agents can load the vault builder docs from one file.
v4.0.0
A major release: typed calls, one-block vault snapshots and a preflight check before you sign. Most 3.x code needs changes.
Cross-chain vaults on Arbitrum and HyperEVM
Vaults on Arbitrum and HyperEVM can move assets to a vault on another chain over Stargate or Chainlink CCIP and count them in their NAV.
v10 on Arbitrum and HyperEVM
Fusion Factory v10 on Arbitrum and HyperEVM, new fuse versions on Arbitrum and a Merkl claim fuse for wrapped rewards on Ethereum.
An OpenAPI description of the Fusion API
ipor.io publishes an OpenAPI description of the read-only Fusion API, and the API docs now start from the v2 vault and market lists.
v3.16.0
Transaction builds and gas estimates can be pinned to a block to match a simulation at the same block.
Compound V3 USDC borrowing on Base
Vaults on Base can borrow from the Compound V3 USDC market and value the position through the price oracle.
v3.14.0 – v3.14.1
Event history can be read from an indexer, and revert errors from newer node software are recognised.
v9 on Ethereum
New vaults on Ethereum get an emergency pauser and can batch their rewards flow into one transaction.
v3.13.0
New tool: vault_validate checks a vault's configuration, the MCP twin of fusion vault validate.
v3.11.1 – v3.13.0
New fusion vault validate command, and public JSON APIs for vault information and Morpho markets.
v3.10.0 – v3.11.0
The vault tooling now supports Unichain, Plasma, Avalanche, Katana and Monad, with a new HyperCore cross-chain example and Aave V4 health per Spoke.
v3.10.0
server_info lists the preview features of the installed package.
Build a vault with an AI agent
A new page shows how to build and run a Fusion vault with an AI agent, and code in articles gets a copy button.
v3.9.0
The fusion CLI can inspect vaults on HyperEVM, and the vault simulator gets a per-block state hook for HyperCore.
v3.8.0
Preview: Fusion vaults on different chains can now work together over Chainlink CCIP and Stargate.
A contact page
ipor.io has its own contact page, and every Contact Us button leads there.
v3.7.0
Support for off-chain positions (External State) grows. The SDK now runs on Python 3.11 or newer.
v3.6.11
Flash-loan callback handlers can be configured from the SDK, with a new Euler V2 looping example on Arbitrum.
v9 and Aave V4 on Base
Fusion Factory v9 with an emergency pauser on Base, and Aave V4 fuses for supply, collateral and borrowing.
v9 on HyperEVM
New vaults on HyperEVM get an emergency pauser and can batch their rewards flow into one transaction.
v9 on Arbitrum
New vaults on Arbitrum get an emergency pauser and can batch their rewards flow into one transaction.
v3.6.10
The config_show tool no longer returns the full node URL.
v3.6.10
Vault reads now go through Multicall3 batches and need fewer calls to your node.
Compound V3 USDC on Ethereum
