# What is Polywrap?
-----
### WebAssembly Development Framework
Composability + On-Demand Execution
---
# Motivation
## "Trad Modules"
### *are holding software back*
Language Specific<br/>Insecure<br/>Not Standardized<br/>Not Upgradeable<br/>Bloat Apps
---
# Web3 Integration Problem
Web3 needs many modules for complex client-side logic.

# How We Build
1. Focus on developer experience
2. Build extendable systems
3. Standardize (alongside adjacent technologies)
---
# Underlying Standard
## W.R.A.P.
WRAP stands for **W**ebAssembly **R**andom **A**ccess **P**rotocol.
**WebAssembly** - A secure-by-default, portable, lightweight, bytecode standard.
**Random Access** - Any WRAP module is accessible on-demand via its URI.
**Protocol** - A set of rules and procedures for loading & executing WRAP modules.
[specification (WIP)](https://github.com/polywrap/specification/blob/main/standard/01.0%20General%20Standard/WRAP%20Standard.md)
---
## Feels Like Magic
```typescript!
client.invoke({
uri: "ens/domain.eth/package/1.0.0",
method: "someMethod",
args: {
value: 5,
arr: ["foo", "bar"],
obj: {
prop: false
}
}
})
```

# Broader Ecosystem Fit
-----
Where does WRAP & Polywrap fit into the broader Wasm ecosystem?
| Standards | Runtime |
|-|-|
| WRAP, Wasi | Polwrap Client |
| Wasm | WebAssembly VM |
---
# What are some example use-cases of Polywrap?
-----
- Universal SDKs
- Upgradeable SDKs
- Standard Interfaces
- Future-Proof Aggregators
- Serverless Function Runtime
- Hybrid Compute (Server + Client)
- Web3 Node Runtimes
---
# Disclaimer
Some use-cases are more feasible today than others.
---
# Project Maturity
-----
The project is still relatively "young". We're building rapidly, and growing steadily both internally within the DAO and externally as an ecosystem.
---
# 1.5 Years Building
