And they are so simple to make. Just: Mint, Nest, Vest.

But what about OTC?
What about escrowed transfer?
Enter Escrow Capsules!

Escrow Capsules

The fundamental ethos of Web3 and crypto is peer-to-peer, permission-less, trust-less, dis-intermediating technology.

In code we trust. Vires in numeris.

From this point of view, use of escrow agents is a security vulnerability that seems increasingly antiquated and redundant, as do escrow fees.

Charged Particles solves this. We offer permission-less, fee-free tech, to be your own escrow service — or more accurately, to let an NFT handle escrow.

OTC in 1 step, not 2.

Here’s how it works.

Creating Escrow Capsules

All 3 steps can be carried out in 3 minutes on And can be performed on Ethereum or Polygon network.

  1. Mint the Escrow Capsule NFT
    Make it simple, or jazz it up with artwork.
  2. Energize the Capsule with the tokens you wish to sell
    As many ERC-20 and ERC-721 tokens as you are selling.
  3. Set the Price of the Capsule
    Set price in ETH on Or if you prefer another currency, set the price on OpenSea, Rarible, LooksRare, etc.

You have put your crypto up for sale with an NFT acting as escrow. All that remains is for your buyer to purchase the NFT and release the tokens from inside the capsule.

Zero fees on
Or the usual fees on other interoperable NFT platforms (2 - 2.5 %).

The Charged Particles community has even started a marketplace to list Capsules for peer-to-peer OTC sales…

About Charged Particles

Charged Particles is a protocol that allows users to deposit ERC-20, ERC-721, and ERC-1155 tokens into NFTs. A scarce NFT (e.g. Art, Collectible, Virtual Real Estate, In-Game Item, etc.) can now be transformed into a basket holding a number of other tokens. The Principal amount can be time-locked inside the NFT, and through integration with Aave’s aTokens, the programmable yield from these DeFi yield-generating assets is just a few clicks away.

Endless applications of DeFi NFTs!
